Stock 3 Speed Standard transmissions

[60short]

Hey All,

The three speed in my truck ( which I believe to be the stock one) is quite un-happy ( second gear has been almost impossible for a while, and first doesn't want to stay engaged without some serious help )

I put a feeler up on one of the local face book groups (looking for a 60-66 3 speed) and got two people that have transmissions that seem to fit the criteria.

If I remember my research from when I got the truck correctly, these were available with either a muncie or a saginaw 3 speed transmission.

Without having my hands on these transmissions, does anybody have any insight if they are interchangeable? I am trying to see if I can swap one without having to modify the driveshaft if possible ( as much of a bolt in as I can get).


I would like to do a 5 speed swap eventually, but at this point, I would be happy to be able to drive it for a bit longer, and not work on the logistics of driveshaft and clutch master and rear diff that should be done at the same time...


Thanks!
Keep on Trucking!!
