Hey there everyone, new to the group and new to working on my 1947 Chevy 3600! It currently has 8 lugs and while the engine is running great, the rolling is really bad. My friend suggested I swap out the rear end. What's compatible with a 1947 and any advice would be greatly appreciated. I'm new to working on cars but my boys (7 year old twins) and I are really enjoying it! Thanks in advance.
