Early grt set up

I have a old grt, #116 I think. Anyone have any set up info for this old car. Where should the rear end be set. The bars are all pointing to the right of the car, / /, shouldn't they be pointed to the center on the rr, / \ . I sent grt a message but haven't heard back yet. I need a place to start for set up on everything from caster, camber, control arm lengths, jbar, springs, ride height.

On a car that old I would have someone that knows them look it over carefully before spending any money on it. The car is going to have stress cracks and possibly some rust that may make it unsafe.
