Muncie ID Help
I currently have a '63 Muncie in my '65. I found a Muncie for sale locally that has the correct casting 3851325 and tailshaft 3857582. The input shaft number is 3952648 and cover number is 39105020. The trans has a 6 cyl bellhousing and was in a '64 truck. Will this work with my '65 with the different input shaft number? I can just change the side cover,correct? Regards, Larry

Hi John, Thanks for chiming in. Not sure what bellhousing is on the car with the '63 trans. I heard the '63 Muncie and bellhousing were unique to that year. I was planning on just getting a '65 bellhousing to go with the 3851325 trans. I noticed the input shaft number was different on the one I wanted to buy. I didn't want to buy the trans unless it will work. The trans is priced reasonably so I wanted to buy it if it will work. Larry

403 bellhousings are plentiful and not expensive - you'll need one.
Do you mean input shaft number, or front bearing retainer casting number?

John, Front bearing retainer casting number number. That's what I meant! I have an appointment to look at it tomorrow. Will it work with the 403 bellhousing? If so I will buy it.

You have the numbers reversed - 3952648 is a side cover (used from '70-up), and 3915020 is the front bearing retainer (used from '68-up).
The main case (3851325) was used in '64-'65, and the tailhousing (3857584) was used from '65-up.
It's kind of a mix-and-match, but it'll work with a 403 bellhousing.
