I'm putting the front end back together on a 72 E body and I am wondering about the caster adjustment. I assume the strut rod is what sets the caster but the FSM has torque setting for each nut. I thought that maybe you would tighten the frame nut more or less to pull the LCA forward or aft, but with torque specs it has me wondering. Other than adjustable strut rods, how is it done?

Thanks
