I'm in the process of rebuilding a Muncie 4 speed. This tranny is a 3.65 out of an 85 GT. I've HOPEFULLY got a 3.32 on the way from Georgia that I'm going to swap the internals out of.
I've got the Kenne-moore shim selector and I originally planned to do a full rebuild and document how to use that tool. I took the cases to a transmission shop and the guy recommended leaving the bearing races be. I'm just going to replace the cone bearings on all the shafts and the seals at this point.
Actually, all of the bearings except for the bellhousing side final drive looked fine. That bearing was on it's way out. The input shaft seal and axle seals were all shot. Synchros look new, but I don't have anything to compare them to.
I'd be interested in knowing where you were planning to get the bearings for the rebuild... Most of the suppliers I've asked say that their suppliers recently discontinued the kits due to lack of availability of one or more bearings.

Blocker rings are dealer only and ~$100 each.
I've already got the kit from www.drivetrain.com. Somewhere around $100 if I recall correctly. Contains all bearings and seals but NO syncros. The current ones look fine to me, but I don't have a new one to use for comparison. Quick shipping, took about 2 days to get here.
The bearings and seals in a muncie are really common. They're used in quite a few different trannys. I have a spare set of new-in-the-box final drive bearings if anyone wants them for cheap. I bought them off-the-shelf at the local auto parts store before I found out how common they were. Here's a link to a thread on OE with bearing part numbers.
This is a really great post!
I'm wanting to rebuild my muncie 3.65 and also ,if I can find one, swap the 3.32 guts over. I would like some more info on the tools needed. The Kent Moore Shim selector kit is needed every time you open and close te case, or only if you swap internals from another trans. Do you have a partnr for the kit please. Could the same kit be used for a getrag (you never know what the future holds)? Are there any other special tools needed Kent Moore or others?
HAHAHA discontinued bearings..... Every single bearing ( minus the input shaft, bellhousing side ) is off the shelf wheel bearings and races from any local auto parts store, Ive rebuilt something like 4 or 5 of them, even did a write up on PenCocks. Unfortunately the pics were hosted on Hemmings which WCF doesnt even deal with any more.
