I have a custom diff and a C4 suspension under my 71. How do I decide how long to make them? Sure I could put tape across each flange and measure center to center and be done. But when I put the suspension at ride height and I adjust the lower suspension arm all the way in the rotor is then and only then perfectly vertical. So I would have no adjustment tighter than vertical. When I crank it out the bottom of the rotor pushes out. Obviously, vertical is fine and you would only add more camber. But do I want to pigeon hole myself to vertical at full adjustment in? Could I make the driveshaft (upper control arm) longer to push it out? Or would I put a lot of pressure on the system by doing so? I tried to put a wedge in the suspension and it was difficult to move the top out very much?
What do you think? Then how much??
Thanks,
Charlie
