1969 Muncie M21 from my Chevelle
 

Based on what the 2nd owner told me about my car, he took the tranny out in the mid 70's and put in a Turbo 400. This was done in Medford MA...Boston area. If anyone has an M21 with the last four digits ending in 7633 please let me know.

Thanks

Good luck Lawrence. I'm still looking for my original m21 too (674703). My brother sold it in a 76 Camaro. The last I saw it was when the new owner stopped at a gas station I worked at ~1990 in Littleton, MA. Grr...

I will need the luck. The second owner took the M21 out in favor of a Turbo 400. That was in Medford MA in the mid 70's.

This is a long shot, but there is guy in Medford who has been slinging Camaro parts since the 70's...i don't have any contact info, but when ever I go to visit my parent and look around on craigslist boston, he is advertising parts, you might look him up.
Good luck.

Still looking....
