You need one from an 85. The 86-87 is different. I ran into this problem a few years ago.
really? what problems were you running into? couse the one i have had in for 2 years was from an 87 and i have know other buddies that have done it without experiencing problems.
May have one from the 85..send me a pic of your connection on it and I can make sure mine is the same.
that would be Awesome! are you pretty sure that its in good workin condition? how much you want for it? and heres a few pics of mine (sorry for the poor quality)
