The O/D conversion to a saginaw 4 speed is not that bad. There are a few tricks. Basically you will need the 3 speed o/d(full syncro model) and a Saginaw 4 speed. Then mix them up. The 3 speed full syncro model is hard to find.
Greybeard,
Glad to hear the trans is working out so well for you. They will work great with stock or moderately hopped up 6's. Tom
