the car will self destruct if you change the front. It was an option put on by ford to prevent this kind of mistake. Just a heads up.
you want to use 87-91 I believe. When did the wheelwell get bigger? Well if your using the 86 fender you want the pre 90/91 extension. If your changing the fenders then go for the late years as ford opened the wheelwell up for the pony wheel. Will help if you ever decide to put a 16-17-18" wheel on thereHope that answers your question.
Also make sure you get the light wiring harness out of a 87-93 too , helps when you start cutting wires
i have a 86 if i were to convert to a 87-93 front end what year fender extension's do i use?
Let me know if you are going to change all the moldings around the windows and everything I would be interested in this. are you selling the quarter windows? i just gotta ask...why didn't you just buy a 87-93?
