How To: Landau to standard B-Pillar conversion with pics

Post by Bill in NC » Mon Oct 11, 2010 10:58 pm

OK guys I'm going to give this a shot, hopefully it will be helpful enough to get you started. Everyone does things different, this is how I did my conversion. It may take me a while to finish this :lol: , so bear with me.

I started out by getting all the parts I could think of before hand so I could do the swap quickly with no downtime. You will need to roundup;
-Standard windows - be sure to think about if you want factory tinted windows (A/C cars) or not.
-Inside upper and lower sail panels from a standard coupe - your b-pillar trim will work w/ both
-New window felts - you may need to trim the length slightly to fit your car exactly
-The black plastic trim that follows the roof/sail panel on the outside - standard is longer
-B-Pillar chrome trim - non Landau standard trim is thin and requires plastic clips to hold the trim to the b-pillar. Non Landau "Classic/Bright" trim is wide and wraps around the b-pillar post and attaches using the factory screws that hold the window roof seal retaining trim to the side of the b-pillar.
-3M windshield adhesive - I used one tube each side. A bit excessive, but there is no room for water to buildup and cause rust problems.

Here is the upper and lower sail panels removed. You can see the 2 nuts that secure the outer Landau trim to the car. Look very closely to the 2 lower sail panel attachment brackets. On the rear bracket you will see a pre-drilled hole less than 1/4" to the right and of the bracket (the other pre-drilled hole is behind the bracket in this picture). Looking at the foward lower bracket you will notice pre-drilled holes 2-3" foward of where the bracket is in its Landau sail panel position. During test fitting and final assembly, YOU WILL NEED TO MOVE THESE BRACKETS TO THE FOWARD PRE-DRILLED POSITIONS for the standard sail panels to fit CORRECTLY.
Image
Remove the 4 brackets that help secure and set the window in the frame. 2 on the bottom, 1 on top, and 1 on the sail panel side.
Image
Remove the Landau trim. Cut the factory adhesive. I used a utility knife with the long flexible blades. You can cut a window out quick w/ one of these.
Image
Image
Image
Locate and save these isolators. You will need them for the new quarter windows to sit on.
Image
Locate and remove and save the screws securing the Landau window felt.
Image
Image
Image
Remove the outside black plastic trim from the roof line/sail panel.
Image
Remove and clean all the factory adhesive.
Image
On the outside find the seam where the standard pillar is seam sealed to the Landau pillar. I used the same utility knife to cut out the seam sealer to leave a nice deep straight groove to cut and seperate the 2 pillars. Some say you can seperate the spot welds from the inside, but cutting from the outside seemed really easy and quick.
Image
Image
Image
At the bottom rear of the Landau piller you will find a welded/braised area securing the pillar to the quarter, a few seconds with a hacksaw blade takes care of this
Image
The top was secured with several spot welds, so I just went straight across the Landau pillar only
Image
I used an angle grinder with a cutting disk for the cut to seperate the 2 pillars. Make sure you do whatever necessary to protect your interior when you start cutting.
Image
There are 3 or 4 spot welds in the inside. I sed a little grinder action and a few taps with the chisle
to get these loose
Image
Image
Ahhh, 1 more spot weld I had forgotten about....almost there
Image
Boo-Yow! It's out
Image
Clean up all those sharp edges and I recommend using your new glass as a template to straighten your window opening lip. GM did not care how warped the lip was while spot welding robots twisted the frames all up. The adhesive and window felts took up the slack so that you would probably never notice.
Image
Use your new window to do as many test fits as necessary. The new window felt is in place in the photo. Also notice the "new" lower sail panel attachment bracket location in the foward pre-drilled holes. We reuse the rubber isolators that the window will rest on and window felt screws.
Image
Now take it back apart and do any rust repair, body work, or painting needed.
I am missing several pictures of using the adhesive to set the windows, so I'll move on to some of the differences between all the standard and Landau parts.
Here we have the windows. The standard window is longer that the Landau window. You can also see why I told you to think about what windows you want to source (A/C or non-A/C)
Image
The black plastic trim that runs down the roof rail and sail panel. The standard is longer than the Landau. These are the pieces that nobody tells you about needing :lol:
Image
Here is a sideways picture of the standard b-pillar trim that needs the plastic reatining clips installed to use this trim. You will need to find a body shop that has a stud weld gun that can do the style you need for the clips or you can use short screws to attach the plastic clips to your b-pillar.
Image
But I would highly recommend this route. The standard window Classic (Bright trimwork) b-pillar trim. It simply wraps around the entire outside b-pillar and uses the factory holes and screws that secure the window roof rail weather strip reatining trim. Takes like 30 seconds to install.
Image

I hope this helps some of you guys out there. All of the parts that I needed for this swap, I bought from members on this site. Thanks again to all the members that sold me the parts to do it.

wow I didn't realize it took all that work. If you never told me it was a conversion I never would have been able to tell. This is a great how-to, and I've seen it up close and compared it to my original Classic B-pillar and yours looks factory. Nice job.

Thanks everybody! The pictures make it look way more complicated than it is. If you have everything to do it there, and have no rust issues (lucky me), you could do the swap easily in a day. After the adhesive cures for a day or so, you can easily cut off any excess that may have squeezed out and install the outside trim. Way easier than cleaning off the adhesive while it's still wet. That stuff gets everywhere quick and takes forever to get off your hands.

appsk8r, tell the wife I said thanks again for the tip on the Classic b-pillar trim. She was the one who recommended them and remembered how it wrapped around the pillars on your car.

lol, I didn't know she noticed. She acts like she doesn't know anything about cars sometimes, but she knows more than I give her credit for.

The only parts that I have left from this swap are the lower sail panels and the outside wide Landau chrome b-pillar trim. Everything else was damaged during removal.
