97- 04 mustang rims again !

I think when it comes to tie rod interference, the common denominator seems to be the "bullit" style wheel. As I mentioned in the pm, I've used two different style mustang rims, same dimensions as you listed, and I haven't any issues with tie rod clearance. This was with two suspension combos, first was a big bolt pattern disc setup from a`75 dart on a `70 340 K frame. The second was with drum brake spindles and ARE's viper brake conversion and big tie rod ends. Both setups used non-adjustable tubular uppers from Magnumforce.
I don't recall reading of anyone having problems with non-bullit wheels with the same dimensions.
I would be looking at the inside profile of the bullits, both from ford and from the aftermarket, as that (to me at least) seems to be the likely source of fitment problems.
