Suspension Rebuild Dilemma!

I understand. So changing the '73 arm to a '72 would not lower the center link, thus providing more oil pan clearance.

Nope. They can't be mixed because the taper in the center link goes in the opposite direction.

Wasn't the change made in '72 not '73 or am I mistaken?

Roy covered it, but the change was '73. Same time as the large ball joint UCA's, single piston disks, body style update, etc.
