I have a 91 supra i'm doing a 5 speed swap on and I need to get a CMC, my question is there a difference between the 86-90 and 91-92's? They look exactly the same in the picture but the 86-90 one is like 40 bucks and the 91-92 is over a 100. Am I missing something or can I just use the 86-90 on my 91?
