You're having the same kind of customer service that I got from those guys. Good products, but you get a different story every time you call. My trans is prior to their "kit", I'm using a modified G force 2004r crossmember. However, my 81 required the same frame extension you're talking about for the later crossmember. It's a 1x3 piece of rectangular tubing that bolts to the original crossmember mounts, and is about 2 ft long. Also bolts to the frame a little further back, and the crossmember bolts to it. If you've got a hacksaw and a drill, you could make one of these from tubing.

Basically, I wouldn't be afraid to try the frame extension route. I'd definitely start there before cutting into the crossmember.

They may be overblowing the tunnel modification. I had to ding mine in 2 spots and cut the shifter hole. Unless they're using the stock 4 speed pedestal, but those are available all over. Although one of the dings I made might interfere with the flange on that pedestal, it's about the same area. Hmmm...good luck

You'll really like the dual friction, Got about 10K on mine and couldn't be happier. Smooth as butter with mechanical linkage.

The driveshaft thing really suprises me. I thought all G body was the same frame, except elcamino. You'd think if they can make a transmission crossmember that fits, they'd have a pretty good idea of where the tailshaft is gonna end up. But then again, they make custom speedometer cables for everything, instead of one or two mechanical adapters. I use an adapter from Forte's. Think their product line started with mopar stuff, so their technical staff has sort of a reverse threaded approach to start with :D

Maybe Rick(iceman) could do you some good. As far as crossmember or extention. His ad is on the home page.

I have been bothering Keisler now several times a week. They have finally told me they have a new contract for crossmembers. The last word today was three weeks to get it. We will see. Its a good thing my car has a lot of work being done to it. I can wait that long.
I did in fact contact Rick(Iceman) but have not been able to follow through. He stated that around $150 or so would be the magic number to fab up what I need. Not too bad. If Keisler was going to take more then 3 months I was tempted. But only after I tried to get my original fixed first.

My UMI control arms came in, new Carb is in. Interior rust is fixed, and clutch just needs to be torqued to proper specs. Once a few more things are complete, Ill wrestle the transmission into place and prop it up for the driveshaft measurement.
Now if only I could get Keisler to send me the sheetmetal and template so I can modify the tunnel!!

I have also taken many pictures, just need to learn how to post that too.

Clutch is in. 10.4 Center Force Dual Friction. Its perty.
Are you running a mechanical linkage? Shafi told me not to use a Centerforce with a hydraulic setup. I can't remember why.

I have a mech linkage.

Why not hydraulic? I wanted to switch someday.

I'm guessing here, cause I've not heard that before. But it would make sense, there's probably valving in the slave cylinder to make it disengage smoothly. The release is powered by the pressure plate springs, the slave cylinder just resists the pressure smoothly. Since the centerforce has super light pedal around the floor, I could see disengagement problems with hydraulic. Like I said, just guessing :-s

The clutch was a 10.4 inch. I replaced it with a Center Force Clutch. The Clutch is in and the bellhousing back on. While I was down there I put the headers in, they had to go in from underneath. Once the transmission is in Ill take a measurement for the new driveshaft. I also got the sheetmetal for the new shifter hump. Small cut is required for the new shifter location. Keisler decided not to send the template so I can know where to make the cuts. I called them today, they said they would call me back. Thay did not.

That last post was to answer what I thought was a question prior to the last post...but then it disappeared. I need more beer.

I am still waiting on the template to cut/elongate the stock shifter hump.
I 'attempted' to wrestle the transmission in the other day but the shifter is just aft of the original hole so it would not fit. I am leary to just cut without proper guidance from the template so I am still waiting....and waiting.
GM Synchromesh tranmission fluid... $10.42 per qt. , that is not cheap.
Tremec takes 3 qts.

Template came and it was more of a complicated cut then I thought. Better that I waited. After the metal was cut it took 10 minutes to get the transmission into the car. Once the transmission was in I jacked it up to the tunnel and checked the cut, very nice. I have bent the precut sheetmetal and now need to secure it in place. While all this is taking place I can now take a measurement for the new driveshaft.
Next in the waiting game is the crossmember. Boxed and powder coated it better fit perfect.
I am getting just a little excited.

I've been following your build up. Keep it up.
I've seriously been thinking of going with a TKO because I just love manual Transmissions. Sorry to hear you've been having a hard time with Keisler.

I was originally thinking of going with a 700R4 but hear many horror stories about the trans....They seem to blow up.

I might just have to wait some time to save up enough money to do the swap. It might just be worth it.


Thanks

I decided to modify the stock crossmember while I wait for Keisler to get their contractors in order. I made a template out of cardboard and "eyeballed" a few dimensions. Then took my handy Black & Decker Jig Saw and cut the 'pad' from the crossmember. Once that was off I chalked up a few lines for the local welder to go off of. The welding shop cut me a new pad out of 3/16 thick sheetmetal to the dimensions of the pad I made. Tacked it on today and I tried it out.
The Cut is perfect. My eyeballing was off 1/2 inch. I need to have the pad slid over to meet the transmission mount and I will be nearly good. The pad needs to have a 'cant' in it as well. I was not able to see this from laying right under the xmember and just drawing lines on it. The pad is also a LITTLE too low as the tailhousing rests on the top of the crossmember insted of the pad. All this will hopefully be corrected tomorrow.
Ill have a pic posted later this week.
My cost... maybe $25. Keisler can kiss my behind!!!! I should have done a T-56 from scratch.

Had the pad moved and 2 small bends put in it. Then I chalked up new lines for the welder. The bends in the pad raised the edge up about 1 1/2 inch. The bends are perfect but I moved the pad too far . With the bends in the pad and me trying to adjust for my first mistake I overshot the movement of the pad and now went too far by 1/2 an inch in the other direction. I tried to compensate for the bends in the pad as they shortened it but its hard to make a good call without ANY type of accurate measurement with just my eyes. Tomorrow I will have it just right. The tailshaft now sits over the crossmember really nice. Once the holes are aligned, Ill be pretty happy.

I'm quite interested in your progress as mine has ground to a halt (all of my own laziness). Would love to see your x-member, as this was also my plan. I thought trying to modify my own first would be best before buying one of the premade ones out there & then modifying it for my TKO. Best of luck and keep posting this info.

PS - I'm planning on not using a console, just a shifter boot. Do you think that "hump" they had you use was necessary?

The crossmember is done. I will take a pic and post it here this weekend.
The new hump was definitly necessary. The cut was very precise and required the hump to be moved back a few inches. The sheet metal covers the hole nicely and provides a place for a new boot.. My only wish was that I moved the hump even further back. Maybe another inch or so. As it is now the new shifter boot I have is not centered on the boot.

My main problem with getting more pics posted is I took them with HUGE resolution. I need to shrink them a little so I can have enough room on my website.

I think the 3/8ths sheetmetal will do a fine job intill Keilser gets me the right one.
Malihoochie, who did you get your kit from? I would like to hear about your ordeal.
Once I get the driveshaft I can try to drive it. I am going to get new carpet too. My wife is sick of my car.

I bought all my stuff piece by piece from various sources. Got the trans from Liberty (local, yet big name trans shop), bellhousing and z-bar from a friend in a trade, pedals from muscle cars only, linkage from Speeddirect, various parts from a friend at a chevy dealer (ballstuds/synchromesh/etc), clutch and flywheel from Hays, and lots of info from this site and a few others. Elcoolmino was helpful too. I have really been lazy about getting the job done though. :oops: I've got 3 kids and they've been the major distraction from the garage. When its two parents vs. 3 kids the cars get slid to the back burner - but just for the time being. Very interested in your x-member mods. Thanks

Malihoochie, did you get the tremec with an offset? How much did the total investment end up costing ? What do you have left to do?
I have the engine tuned and just need to adjust my linkage. Seems like I have a very long pedal throw to engage or disengage the clutch. Is there a way to shorten this?
Once I get driveshaft... I CAN DRIVE IT!!!
