Weld has a new wheel that's supposed to be shipping at the end of this month. It's 15/3.5". A few people on Modular Fords have them on order so I'm just waiting to see what happens with them. According to Weld, they're supposed to fit with no modifications or spacers.
Yep. The 15x10's will be out soon, but the backspacing is wrong (I believe it's about 6"). They'll stick out a little (which is fine if you're not lowered). There's going to be 15x10 with about 7" backspacing coming out late summer I believe. That will fit perfectly.
