Doug,
On the 1939 Chevrolet, you said you put highway gears in, did you use the original housing? If yes, how did you do it?
Thanks, Victor
Hello Victor,
We actually used the 1940 rear end and adapted the 39 drive line to that because we had a set of NOS gears for the 40. I recall a little machine work to make it happen with the drive line.
It may be possible to use an aftermarket, early replacement universal joint rear half with the original front half in order to couple the 40 driveline. I know that works for the trucks. Some of the better quality joints won't work because they were the needle bearing style, instead of the early style, solid bearing type. Finding gears is the hard part. I don't know if there are any new gear manufacturers. Sometimes those are noisy and inferior quality. I installed a Borg Warner Overdrive in my truck. It works very well. That requires a lot more machine work and engineering. I have another case and extra gear set for the OD.
There are some options for you to think about if any of that interests you. I think I have one of the universal joints that I spoke of earlier too.
Thanks for asking, Doug
