I have a VERY NICE unstained (P7 T 27) M20 Trans with NO VIN cracks, damage or repairs ever for sale. On the main case it shows 3885010. On the tail shaft cast # is 3857584. This would work great for any GM car built during the months Jan/Feb/Mar of 1967 that is missing its original transmission. This transmission was placed in the following GM vehicles: 1967 Camaro, 67 Chevelle, 67 Corvette, 67 Impala or 67 Nova. It was in my running driving 69 car and has been since pulled and cleaned. It’s has a nice clean brilliant aluminum color with no staining unlike so many others seen in the classifieds or EBay. It shifts very nicely, no pop out or sounds. This is a drop in and go M20 Muncie, $700 plus actual shipping cost. I will get more pictures posted soon. No disappointments.

Thats a pretty good deal

Oh it would be so nice if it were an M-21. Mine was stolen in the summer of 1968 as my brother in law left it sitting in the driveway and went to the autoparts store for a new clutch. Came back to realize some people are not very nice.

Robert,

Just a bit of gee wiz info for ya, the 67 Muncie’s don’t have an A, B or C stamp on the case indicating what they are. The only way to physically see what it is, is it to open it up or remove it from the car and look at the input shaft. Obviously the 22’s have a very identifiable sound of their own, but 20’s and 21’s sound the same. So with that being said, this is waiting for you. I’m selling it for exactly what I had to give to get the right trans for my other 69. This is a really good deal for who ever needs a NON-VINed 67 Muncie. I’m really shocked I’ve had no response to date.
