I’m gathering parts for my T5 5spd conversion and I want to make sure I buy the correct rear end / differential. My truck is a 1946 1/2 ton. I need an open differential and had read on the threads that any 1955.5 through mid 60’s Chevy truck will work well. Is this correct? What year model differential assembly should I be looking for? (Wanting to maintain 6 lug wheels).
