new to site and (go figure) body alignment problems
 

This site is great. Just reading through the previous threads has helped out quite a bit, made me feel a lot better in dumping 9 grand into a rusty 72. These things are addicting. One thing that I read about was shimming the body mounts to adjust the alignment on the doors. I'm not quite sure how this works and any information would be a huge help, as there are some serious gaps b/t the window and the frame. I'll try to post some pics, it comes home from the paint shop in a couple of days.

Pleased to meet you! Maybe when you get a chance, update your profile with where you hail from so we know if any members are your neighbors! :)

The body tub is fairly flexible, especially if there is rust damage in the floors and rocker boxes. Shimming the mounts essentially bends the body. In gereral, shimming the mount at the front of the tub will have the most influence. To open the gap between the door and windshield post, add shims between the rubber mount and the body.

It is also possible to adjust the position of the door in relation to the body tub. Unfortunately you have to remove the fender to get to the bolts. Adjusting the door hinges has the most effect on the overall distance between the door and the rear 1/4 panel, and between the door and the rocker panel.

To really get it lined up well you need to shim the body and adjust the door at the same time.

Good luck, look forward to the photos.

Hey SB thanks alot. The main gap that I have is b/t the window and the top, but I'll screw with it, I think I can get it to close. Maybe I should start a new thread but, I also just picked up some sweet seats from a conversion van that spin all the way around. I know that I have to chop the post a bit, but I was looking for an idea on how to mount the base on the floor. It's basically a 6" pipe attached to a baseplate that's about 12" square. My blazer's interior is basically a tub so anthing that will work. . . will work. The van has an electric bench/bed that's perfect too for only $15! Whaddya think though, a little cheesy right? Would be nice at the beach etc. though?

Best tool to get consistant gap @ seams= paint stir sticks. They are made of wood, so they are easy on paint jobs...and they are cheap. They are also the ideal gap between door/fender.

*ALMOST IMPOSSIBLE TO ALIGN THE DOORS W/O THE TOP ON ;)

ON Blazers, the first gap to go after is the rear of the door to the front of the quarter panel. This needs to be perfectly parallel while having the leading edge of the door quarter window frame aligned to the windshield frame. This is all best done with a hardtop in place as this will hold the windshield frame/firewall solid. Everything else is easily adjusted (fender, rocker panel, etc.). The front of the rear quarter and the outer rocker are at right angles but if off, that's were the shimming of the body. The GM assembly manual refers to shims under the front two tub mody mounts. Easiest way to to slot some large washers and use them to adjust the flex of the body depending on the alignment problem.

not to hi-jack this thread, but will you have to worry about the same thing when removing a 3" body lift and dropping down to the regular Poly mounts?

East end K5-----assuming that your existing body mounts are ALL equally sized in relation to your urethane replacements, you will not have a problem. (ie: youe existing body pucks are all 3'' larger than your new urethane bushings.)

What if you have a windshield frame that's has rot cut out with top off. Since I can't put top on now until windshield frame is repaired what is the best approach for that?

Holy blast from the past!!! A 10 year old thread refresh!

No help with your question but congrats on the thread bump.

Been stuck for weeks now going through every thread i can fimd but no luck. Ugh!

LOLCI (laugh out loud crying inside)

Re: new to site and (go figure) body alignment problems
 

Only thing you can do is get a piece of tubing and make sure the door opening on either side is square. Then tack well in the tube on either side of the upper door opening to keep the door gap from moving. Then adjust as needed. The tubing will do what the top does to hold the body in place. That's all I got. Good luck.

Or don't put the top on

Okay thanks. I think I got it.

I have quarter panel off for repair.. I'll bolt it back on and square everything up and tack in bracing.
Then repair rockers and cab floor with repair panels
Remove tub for sand blaster.

.....oh and I never planned on putting top back on. Good point GMCYA68.

Thanks guys.
