Note that while stock 15" wheels will fit on the 14MM studs, the lug nuts destroy the wheels. Either the taper angle is wrong, or the lug nut itself is too large a diameter, either way it ruins the tapered seats in the wheel that the lug nut is supposed to snug up against.
Ok, now I have a noob question of my own, thinking back over my 14bff swap. I have a set of stock 1982 wheels and a set of stock 2004 wheels. I'm running standard 1/2" studs on the front and 1997 metric studs on the back (G3500 van axle). I've not noticed any issues with lug nut compatability. Am I missing something, or do the FF axles not have this lug-nut-destroying-the-wheel problem?



...hadn't seen that one before...
