Avoiding Tweaking Blazer Body?? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Huskerboy2 · 06-05-2004, 08:02 PM

I've heard people talk about tweaking the body of their Blazers out of alignment before. What are the dos and donts of replacing body panels and installing patch panels on a Blazer. For example, If I keep the top on my Blazer and keep the tub on the frame, can I pretty much remove any body panel I want to and cut out any rust and weld in new patch panels without worrying?

The main reason I ask is that I've got the top on my Blazer right now and the tub is mounted to the frame. The tailgate, doors, etc. are all off the truck. I need to remove the rear cross sill that runs across the back just under the bed because I have some rot that has happened along the rear of my bed due to moisture being trapped in between the rear sill and the bed. Can I do that without fear of tweaking anything? Do I need to rig up some bracing or anything?

Thanks everybody.

I'm curious too, I have to put new mounts on mine, top is coming off too.

I replaced the body mounts, pillar ends, inner and outer rocker panels, and some patch work on the floor. I put my top on before I started cutting, and I still got some minor movement. It was not enough to cause any problems, but next time I would weld in temporary bracing.

A few weeks ago I put out a thread about some braces I saw in someone's
blazer pic's, I have yet to get a response from the correct person. Removing
body off the frame and I want door braces and a tailgate brace. I guess if
I could get factory spec's I could build some, but I don't want to go off of
what I have now because rocker boxes are junk and windsheild moves when
you open the doors just slightly, I to could also use some advise on this....

Jimmy72Custom, did you have your tub on the frame and you still got movement like that??

I had the tub on the frame. With the fenders off I jacked up the body one side at a time and replaced the body mounts With the front fenders off, and the rocker panels cut out, if the cab supports and pillar ends are rotten, the windshield frame / firewall will move freely. Putting the top on and checking door clearance before cutting out any metal will get you by. If you are taking the tub off, I think I would weld in temporary supports to hold the fire wall in place if metal needs replaced.
Just my opinion:-)
