NOT TO CHANGE THE SUBJECT BUT I HAVE A 68 SS427 L72 CAR. IT HAS 15 INCH STEEL WHEELS WITH WHAT LOOKS LIKE A PF CODE AROUND THE VALVE STEM. DOES ANYONE KNOW IF THERE WAS A 15 INCH WHEEL OPTION FOR THESE CAR? ALSO HOW CAN YOU TELL IF THE TRANS IS A M21 OR M22 WITHOUT TAKING IT APART? ALSO IT HAS A DN CODE ON THE REAR. ISNT THAT A 410?

That is a 4:10 posi prefix for a 1968 Passenger.

On the build stamp on the trans it should end in a letter A=M-20, B=M-21, and C=M-22. Not all trans's have this suffix but most should.

I THOUGHT THAT WAS 69 AND UP. ONLY THING ON THE SIDE ARE THE DATE CODE AND THE VIN NUMBER.

NOTE THE 6000 REDLINE AND THE SS427 ON THE WHEEL

I too think the A-B-C definition codes weren't used until 1969 +.
Maybe crash could help clear this up.

I believe you guys are right. I wasn't paying attention I thought it was a 69. Here is a picture of a 69 trans stamp I have . I will post a picture of a 67 with no stamp later.
Don getting back to how can I tell if it a M-21 or M-22. I have not been in a "QUIET" M-22 car. Does the trans wine at all.

Do you have a picture of the input shaft? The part that sticks out of the transmission.

the 66 went for $56,000 (thursday night at Barrett Jackson), I was watching. The Buyer got a bargain in my book.
A beautiful Big Block Big Car with evry bit of documentation you could ask for. Better than a Hemi clone, The Real Deal L-72.
Congrats to the seller, however I am sure they will miss the car.
