I want to replace, not repair, the rear end on my 47 (first series) 3/4 ton truck. I would like to replace the (8 lug) rear axle that is currently in it with another 3/4 ton (8 lug) in order to get more modern brakes. Can anyone tell me what rear end would fit? Also considering the same for the front. I am in the process of replacing the 216 with a 235 out of a 1957. I will probably replace the stock 3-speed w/ a T5(?) in the future.
