Re: 3 spd transmission opinions wanted
The single-stick transfer case is probably a Dana 20 or a Dana 300. Both have a centered rear output shaft. Your '63 probably uses a Dana 18 which has a passenger-side rear output, and goes with an offset differential in the back axel. I'm pretty sure your '49 will have a similar arrangement. If that's the case you can't use the newer transfer case without doing a rear axel swap too.
Frankly I would rather have the Dana 18. It shifts much more smoothly and doesn't get hung up in 4WD the way the D20 does. Don't know whether the D300 has the same problem.
