Question 1972 GMC 3/4 ton alignment?

Does anyone have the alignment specs ( toe in, caster, camber) for a 1972 GMC 3/4? Thank you

Re: 1972 GMC 3/4 ton alignment?

I just make up my own specs to get the truck to drive how I want. I am currently running with 3 deg pos. caster, 0 deg. camber, and 1/16 toe in. If the truck seems to wonder too much with these specs add a bit of toe in. But with radial tires I wouldn't go much over 3/16 toe in.

The GM servive manual doesn't list figures. You have to measure the angle of the frame off of level,then measure caster,add the two together. Now measure where the spring mounts,between the upper and lower arms. Then you plot the results an a graph.
