This is on my 68 which was built in late 67 car is dated D07.
It's a 427/390hp l36 with a 4sp, not sure if the 4sp is m20 or m21 because in 68 they didn't put the code indentifier on the end of the transmission number to tell if it's a m20 or m21..
here are pics of the rear end I can see the 67 date code which makes sense for my car so it's the original rear end just not sure on the ratio which I know theres other ways to tell but wanted to see what it was stamped with see if you can make it out I sure can't.
Some of you guys that know what to look for might can make it out I took a lot of pictures some show the part that I can't make out better than others, if someone could make that out and I know for sure what came in the car that would make my day
the last few pics show it best
