Are you looking at changing your truck from a column shifter to a floor mounted style (mounted to the transmission case/tailshaft housing) shifter, or something else???

From my previous thread reading, I'm pretty sure others have done that very swap. Perhaps those that have will chime in with their experience and input?

It will have an open drive shaft and it will be a better transmission. The old "peanut" transmissions were never offered with an open drive shaft and no one ever produced one. | | | | | Joined: Feb 2004 Posts: 29,933 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,933 | Since you'll need to fabricate a custom driveshaft anyway, try swapping to a Saginaw 3 speed with a synchronized 1st. gear. With a little creative fabri-cobbling on the shift linkage you'll still be able to use your original column shift setup.

I see that you are a few posts shy of graduating from "Moderated Status".
Make a few more posts so that we can exchange via PM.
I have exactly what Hotrod Lincoln is describing. A 1965 Saginaw 3 speed transmission with all of the shifter arm and shifting linkages modified for tree on the tree in an AD truck.
Send me a PM once you are no longer in moderated status for more info.
