10.5" rear wheels on '90 GT?

[HaynStang]

Looking at some 10.5" wide rear wheels with 27mm offset... What needs to be done to make them fit? What range of tire sizes would I be able to run? I'm converting to 5 lug, obviously I'll have to keep the stock track width with these wheels...

Fox length axles are a MUST! If you don't have the stock length they will stick out of the wheel wells considerably. SN95 axles are 3/4" longer than the foxs' are so don't do it that way with 10.5". You also must remove your quad shocks, and bang in the frame rail. I would also recommend rolling your quarter wells because 10.5" wheels on fox axles will be even with the outer edge.
