I am picking up all the parts I will need some day to do the Driveline swap that I would have in my ideal truck.
I am starting by getting the front and rear end from a 53 half ton that I will be able to put in my 1950 GMC half ton. I am doing that so I will be able to have the more common and easy-to-use Bendix brakes. Currently my Huck brakes are fine but I know at some point I will need to rebuild them so I might as well change the type of brakes at that time. However if I go through the trouble of making that swap I might as well make a swap to more Highway friendly gears and an open Driveline.
I understand that I can change the sm420 over to and open driveshaft by finding a currently open drive sm420 and swapping out the rear parts of it. And at the same time by going to an open Driveline I can get some more Highway friendly gears such as either 373 or 390 gears. I'm having a little bit of difficulty figuring out what years I can use parts from.
My searches have pulled up lots of little tidbits talking about possible swaps but I have not been able to find a definitive range of years and gears that would be found in those years of parts.
Any information on what years I can start looking for for trucks or chassis to get the parts from would be a great help.
Thank you.
