Hot Rods 51 Chevy coupe axle swap

Just bought a 51 Chevy coupe with stock drive line . I’m going to swap in a 350 and th350.. has anyone ever put a Pontiac/olds 9.3 in their 49-52 .. I have two of them laying here waiting to be used

 

Well I am sure you would not be the first.

 

My Son has a 50 Chevy coupe nostalgia g***er. He has a 9.3 in it. He found a 57 Olds housing (only year for leaf springs) and other than slightly spreading the rear springs, it was a bolt in.

 

Are they 1957 rearends? The narrowest of the 9.3’s

 

I checked my Fabcraft book, it does not list the housing lengths. However, it states for any given year, the Pontiac housing will be wider than the Olds. Also, the rear brakes and backing plates are varying sizes and can affect the overall length.
