I am in the process of renovating my 1976 911, I want to make sure I am supporting it correctly before I conduct any significant repairs. I would like to understand what is best practice with regard to supporting the body/chassis (engine, running gear and suspension all removed).

What I am currently observing is that when the body is supported on a rotisserie (fixed to bumper shock absorber mounts) the door gaps are spot on however, when I lower the body on to axle stands rears under torsion tube and front under front foot wells the door gaps degrade mainly closing up where the top front edge corner of the door window and body window frame. This is opposite to what I expected.

Any advice would be much appreciated.

Regards
Mark T

C4ME,

Many thanks looks like this type of jig would be used as a reference to get either an accident damaged car straight or you are doing major panel replacement. My car is very straight and original, just kidney bowl's, and general tidy-up.

Cheers

This was the shell that I'd planned to use to form the basis of my '73 2.8 RSR.
Roof and outer sills removed (prior to acid dipping).
You can see the two braces welded into the door apertures to ensure the shell didn't twist in this area.



However the shell was also mounted onto a frame :



which supported it (squarely) from the torsion bar tube ends at the back of the shell (I can't remember where the front of the frame picked up the shell, but probably here IIRC) :

Slippy, very helpful, this is very close to how I am supporting, I just need to move the front supports from the front of the foot well to the front torsion load points, will see if this helps tomorrow.

Thanks to all, perfect door gaps all round.
