Well, I got the correct 1970 - 1974 calipers and hoses on the car and the spindles swapped side to side to get the calipers front mounted. This has solved the interference issues with the lower control arm. My lines and distribution block / valve won't be here for a while so I'll have to wait until this weekend when I get back from a business trip to test drive the new caliper set up.

Does anyone know where I can get the info to properly set up the booster pushrod?
