I checked the shafts that came out of these lower control arms and they appear to be the exact same measurements, distance from the ends as well as distance from each other.

Am I missing something here, are the majority of the 1.5 inch measurements I've seen on this site from 72 and older trucks, or 3/4 ton trucks with steel bushings?

Any insight would be greatly appreciated.
That is one of the things we are trying to figure out right now and why everyone is trying to add as much info as possible. Thanks for adding your information to the thread. Hopefully, with guidance from BMERDOC and others of his caliber on this thread, we can make some sense of things.
