my 1940 chevrolet service manual says the Special DeLuxe and Master DeLuxe came with 4:11 rear axel ratio , the Master 85 came with 3:73 rear axel ratio. Houseing is stamped with B + number for 4:11 or C + number for 3:73.
I want to swap the 4:11 ring and pinion from my 1940 suburban 1/2 ton and use the 3:73 Master 85 car ring and pinion . Any done this? Does the closed drive shaft drop down from rear of transmisson so the rear end assy can be unbolted and removed without un hooking bango houseing brake lines ect.ect.
