M35A2 Transmission Swap ?

[Smokindieseldually]

looking for some advice. 1971 m35a2 , started getting a knocking in 5th…. Have not had time to pull the cover off and inspect yet. I’m located in Canada so parts have been somewhat difficult to find ! Question being I did locate a spicer 6353 and a spicer 6352 locally… with a bell housing swap would either of these transmissions be compatible in my deuce ?? Thanks in advance!

Dig in and find out what the issue is before you spend any money or waste time on collecting parts.

You'll be time and money ahead.

No, not compatible at all...
There simply is not enough room for a 6352, it's almost twice the size (and weight) of the 3053. It also has a larger input shaft and output propeller flange.

Most likely you will find your 5th gear with one- or more broken teeth.

I was about to say the same, and is there any transmission that's close to the same size as the 3053 that would have a better overdrive? I was thinking of the Eaton 11605A but they're hard to find and I'm not even sure what's the size of it

Spicer bellhousings and input shafts are ALL interchangeable with each other. Least some engineer had a brain.
