I would suggest yuo contact a local Mustang performance shop. I have two friends that own shoips and they both part out Stangs on a regualr basis. They keep the harnesses and upper and lowerrs. Their customers often go to the Edlebrock setup. So they have everything you need to do the swap. And i would bet if you offered them $1000 you would probably get a BJ thrown in. My friends sell them at swap meets for $500 all the time. to them it is just garbage, but instead of tossing it, they get something for it. In most cases it probably pays for the car they stripped for parts.
I would assume that two Brantford shops dont have the monoply on this, and you can get this stuff locally.
You could just buy your own used mustang, strip it yourself, and sell the extra parts to make it a free change over for you. Now I am not certain what all the EFI parts fit on block wise. But I think they go fairly far back.
