It is a fact of life that anything that followed the very popular '36 would be very difficult at it's best.
The '37 Ford had many modern improvements that were carried through to '48, of course the cable operated brakes were not one of them.
I was able to use '37-38 rear radius bars on a '47-48 Columbia, that bolted right onto the '36 torque tube and center section under my '36..
