The tansmissions are the same length the only differance is the slip yoak and I have both.I have done some research I found that the saginaw used was pretty much the same from 66-87,and basically no change from 66-76. I was hoping someone knows for sure what was on the 66. I think my arms are off a 74,had to buy another transmission. The shifter arms were missing,so I,m trying to use what I have. Does anyone have some off a 66 for sale?
