When I originally purchased my car, it was missing both the engine and tranny. The car didn't have an column shift setup and the dash and column were still the original shade of black. The center tranny tunnel looked like it had been cut out larger than needed on one side, but was told this car was raced at a local drag strip for a few years before I got it. It only had a automatic pedal setup at the time, but in the trunk I found a manual pedal assembly along with the z-bar, etc. I was pleased to find all the brackets factory welded to the frame for the factory 4-speed. I was just missing the center console to put between the bucket seats.
Couple years after I got this car running with a 350 and TH-350 tranny, I started to try to find a Muncie for it. I had a hard time finding one cause noone in my area wanted to part with them, I even knew some guys were buying cars at auctions just for the Muncie. A friend from high school happened to end up with a spare Muncie, but at that time I didn't know how to tell if it was a M-20 or M-21, and we sure didn't know there was a difference in the years. So I purchased the Muncie from him and placed it in storage. I knew I would be restoring my Chevelle and figured it was better to have something to start with then have nothing at all.
After I purchased my first house 14 years after I bought my car. I finally had a place to build my high school hot rod like it was meant to be. I started looking into Muncies and found out that the tranny I had was a 1964 M-20 tranny. And further research showed that in 1966, the Muncies changed from a 7/8th inch counter shaft pin to a 1 inch pin. So I started looking again, and found a guy that had been rebuilding Muncies on and off for 30 years. I had him build me a 66-67 cased Muncie M-20 4-speed. It was built using all new internals and the guy that build it was trustworthy and honest. And I got exactly what I wanted. His business is Manchester Muncies out of Manchester, Iowa.
