Wheel tubs

Post by Strokin » Sun Oct 05, 2014 8:46 pm

Doing my first backhalf. I get conflicting info on how to attach wheel tub to quarter panel. Welded or sealer? On a Monte Carlo ss. Also any ideas on trunk hinge? Just move them in?

Is the body work already done? If so, you cant weld or it will burn through the paint.. Use a seam sealer or silicone.

go with the seam sealer it won't absorb moisture like the silicone will.

DO NOT WELD! You will warp the quarter panels, even if you do body work it will show some time down the road.

Fit the tubs to have a 1/8" to 1/4" gap from the edge of the tube to the inside of the quarter panel. Do not fit the tub tight against the quarter panel.

We use urethane seam sealer. Put tape on one side and apply a bead to the opposite side, allow to dry, then remove the tape and apply a bead to the opposite side. Trapping the edge of the tub between two beads is the strongest method.

So welding tubs to the inner skin or old tub isn't an option? Or is there not enough left?

You can leave the outer wheel well and fabricate a new inner that is moved in.

If you just do the inner wheel well all you need to do is remove the factory hinge brace and make a new one to attach to the squared off fabricated inner tub.

If you do a full tub then you may need to modify the hinge depending on how high you mount the tub.

Ya it's a full tub, 33 x19.5x15. So pretty sure tub will be to tall.

Your either gonna need to fabricate a custom hinge, or like myself I removed the hinges completely and went to a fiberglass deck lid that is attached with dzus fasteners.

So started my backhalf with frame off. I purchased a separate frame for project. Looking at my existing car with body on frame, it appears the 33" tires will rub on quarter, unless I move axle centerline back. How's people experience with this? Minor body work? Move centerline to your desired spot and change wheelbase? Help plz

To clarify, it looks like it would rub on the front lower portion of wheel well, but has lots of room in the back

with that tall of a tire you have no choice but to stretch the quarter panel opening.

If the back half is already done your limited to how far you can move the axle as is. I limit threading 4 link bar rod ends out to 5 turns most of the time. If you wanna move it back a noticable amount then new longer 4 link bars may be needed.

You can center the rear in the opening how you see fit really, just look at it closely as you do to make sure it looks in proportion and doesn't look odd how it sits.
