I recently got an 84 GT t-top 5.0 5 speed but the engine is no good. I also have a 95 GT 5.0 Auto I was thinking of swaping the engine from the 95 the 84 since the 95 is crashed. My question is if I need a different ECU if I am going to use the 5 spd transmission or anything else that I might need. I know they are not cobras but I don't know of any other mustang sites since just recently got these stangs and been posting here on the Lightning section.
