To give you an idea of where I'm at, I have seperated the body from the frame and have finished with the chassis work. I am in the process of replacing floor/trunk pans on the body and would like to place the body on a rotisserie. I talked to a gentleman this weekend at the Autofair about this and he was very adamant about not placing the body on the rotisserie without first mounting it back on the frame. He said that without it, the body would twist and the doors would never line back up properly. The car is a '67 Chevelle. Any thoughts? I just don't see the frame being that sturdy. When I had it all broke apart for paint, it was as limber as a rope. Second question, where would you mount the rotisserie to, the body/frame mounting holes?

You had better listen to him, he is a wise man. There is no better jig then the frame.

That's strange, many many people have done body off frame and on rotisserie with no problems.
Now if it's a convertible you do need to brace it between the door openings.
My 70 convertible body is bolted to the rotisserie at the front body to frame bushing holes in front and to the four bumper mounting holes in the rear.

The whole purpose of a rotisserie is to have the body off the frame and to be able to turn it upside down.
If the body was on the frame it would be too long to even put on a rotisserie.
Is it possible the guy meant that the floor and trunk pans should be completely welded before the body is but on the rotisserie? That I can understand. But if the body is complete there should be no problem with it twisting...

I turned my 68 on it's side (see 68 body pic in sig) with it bolted to a dolly and I never had any problems...

I looked up the Chevelle rebuild that Goodmark did on the Super-Chevy website and they have many pictures of the body on a rotisserie without the frame. They even have one picture where they give you a view looking straight down the side and are bragging about how slick the body is. As for my floor pans, they are already fully welded from the top side. I'm wanting to get to the bottom to clean them up and paint. I think that I'm going to set it in the rotisserie without the frame attached. If anyone is interested, I'll be glad to report back as to the results. Might be a little while though.

As always, thanks for all of the help and advice. Just hope to be able to return the favor someday.

Sounds like the guy thought that you were telling him that you planned on doing your pans while it was on the rotisserie.

My understanding is that the pans should always be worked on while the body sits on the frame.

I plan on doing the same except I am going to remove the body, do the frame, put body back down, then do the pans. Why? Because I got a body mount that is whacked and the body is not sitting correctly as it is.

You can do body work on the rotisserie. However, I have to agree, the big stuff, like replacing panels, floor pans, trunk pans are better off replaced while the body is on the frame. It is firm and I agree, there is no better jig.

My 66 sat on my rotisserie for over a year while it got ready for paint and I had no problems with the doors. Didnt have to replace any panels or floorpans.

from what i understand,
do not replace any panels while the body is on a rotisserie - the body will twist.

on my resto, i pulled the body off while im restoring the whole chassis and when that is doen i will drop it back on the frame and the do the body work like replacing the quarters and then pull it off again and have it painted, the resume with final assembly - of course i just simplified the next few years in just a little paragraph...

the way i look at it, id rather be safe than sorry... i agree with "the body's best jig is the frame"
