Thanks! That helps a lot! So I'll go with 73+ upper and lower ball joints, 60-76 control arm bushings and new upper cam bolts.
I wonder if the pitman arm is pre 72, thus causing the oil pan clearance issue??
Nope. The joint on the '72 down pitman is opposite from the 73+ pitman. The '72 down pitman points up (comes up through the steering link from the bottom), the '73 up pitman points down.
