I've got an '85 GT. I was going to order a suspension kit for it this weekend. But where I'm getting it. It's only listed for a '86-93. Some one told me here on the forum that the front spindles were different. So there were different struts.
Well I did some parts number searches. And I'm more confused now. There is a different part number(for struts) for the '79-'85. But the description shows that it's compatible with all fox bodies. But the number( for struts)for an '85-'92 is different. But it only states that it'll only fit those years.
So... does anyone know the difference? And if so what? I'd really like to just order the whole kit. But if it won't work I'll just shop for individual components for my car.
