I am here, had a VERY EARLY start that just did not seem to end.
I did see the post on my PDA, but,,, was in the Doctors office at the time...
Ok, in my opinion, we are looking at 1957 to 1962ish suspension off a regular 1/2 ton Chevrolet truck.
One thing you can do to isolate it out a bit is to pull the race and get the stamped part number off of it. Then go to any parts store and they can cross reference the number to ensure the year and in some cases the application.
You will find that if I am correct, then rims from all of the 4WD Chevy's that had 6-Lug suspension will fit right on. If so, then the suspension is from the range listed above...
There is a GREAT chance that newer hubs will fit, possibly up to 1972.
