If you’re diving into a classic ride from the early '60s, you know how crucial it is to keep that Muncie transmission in tip-top shape. This Muncie Model 20 M/T Bearing Kit is your go-to for getting your 4-speed manual back on the road. It’s designed for '63 to '65 models, and trust me, it’s built to last.

This isn't just any kit; it’s got everything you need to breathe new life into your transmission. We’re talking about a solid aluminum case with a seven-bolt side cover. The main case stretches 10 inches long, and you’ve got options with either a 10 or 26 spline input. Plus, the counter gear shaft measures a sturdy 7/8 inch in diameter. It’s like giving your old transmission a fresh start.
