I didn't think the 73-87 was quite as simple as bolt in.
Clipping a 58 I was flowing this thread and I could have the clip rebuilt and ready for install for about 350 with new parts.
It would lower the truck and cost less than a drop axle and front end rebuild.
It should make a nice steering and stopping vehicle that my wife would like to drive.
One of the bigger challenges would a power steering pump.
