Anybody in the Sonoma, Napa, Marin area that has this tire/wheel combo that would help a brother out? I want to check for fittament before I convert to 5 bolt. I want to put 1 lug nut in, undo my shock and check clearance.

6" or 7" and what offset??

a 6" will fit perfect, a 7" might need just a "little" rear fender tugging or lip rolling

I'm coming from the land of 2 Litre alloysI thought that they were the same. All 6x16, all 7x16. How can I find out?

16x7 Phonedials on all 4 corners (23mm offset which is the common 16x7 Fuchs offset as well) with 205/50's

great fit up front, on the rear I had to roll the fender lip and tug on the fender near the back half to prevent tire rub.
