I have no way to machine out the hub, so that would be farmed out. I can install the longer wheel studs, but if I add that in, the spacers, the rims, new tires (or good used ones), lug nuts and washers, the cost of machining out the center, I think I would be better off finding others. Just wish it were bolt on as I have a fuel injected project that is taking most of my time...... oh, and building a new garage :D..... time is short, bolt on and go sounds better at the moment :)
