birdog, your bolt pattern is 5 on 5.5".

I'm not sure of your stock backspacing, but I think it is 4.5" on a 2WD. The reason I say this, is that my spare wheel measures 4.5", and I think its for a 2WD.

Ford used the same bolt pattern on all F-150's up through '96. In '97 they changed to 5 x 135mm.
