I found a 1982 LX coupe, its been parked for a while and the guy wants $150 for it. I have an 1988 GT/LX, but Ived always liked the coupes. The thing is that the guy lost the keys for the coupe. Can I swap the ignition switch, and all the other stuff that needs a key from my Mustang to the coupe? What other parts can I swap?
