A buddy picked up a 4 speed with shifter, then found out it is from a 1967 AMC. It has 4 rings on the input shaft he says. Of any value for anything other then an AMC?
I had a T10 from an AMC and it had the same bolt pattern as a GM but I understand that some have a different pattern. The input shaft on mine had a different length on the nose of the input which can be machined to fit Chevrolet applications?
If it doesn't work out for you I have some AMCs with four speeds and don't have a spare. The inputs are longer on my 69s than GM. 67 I don't know for sure.
