Swap

If the rear does not need to be original... It should be pretty easy to make another rear - I am sure the wheel bolt pattern is 5 on 5, 1/2 x 20 wheel studs.
You just need the over all width drum to drum and we can suggest some rears that could work... Also we can totally build a NEW rear with what ever specs you want.
Just need the spring perch width center to center mounting hole, spring metal width to know what width perch to install (IE 2" 2.25" 2.5" etc)
What gear ratio do you want? Do you want positraction?
ANY rear can be used as this is a leaf spring set-up and you only need to get the width correct and then cut all the other stuff off the housing and install your perches with the correct center line and pinion angle.

Any 1937 thru '47 Olds (or Pontiac ) rear end center sections will bolt in to your '37 rear axle housing .
'48 thru 56 centers can also be made to fit by grinding the housing some so that the ring gear will slide in .
Hydra-Matic center sections offered much "higher " ratios (3.42 or 3.23 )that are much better for high speed cruseing than the original 4.37 gear .
I put a '54 Hydra-Matic rear center in a '37 Pontiac and it would easily cruise at 65 MPH.
