Hey - thanks for your interest! I am still waiting for the calipers to get back from Calipers Online. I should have them in a couple of days. Also, I have new lower ball joints on order, should be here tomorrow. Meanwhile I've been cleaning and painting spindles and stuff in between rain showers. I showed my stud issue to a friend who is a mechanic and he said they were fine. So I used a lug nut and a spacer to pull one through but the threads seem to have bottomed out just a hair before the top of the stud made contact with the new rotor so now there is a gap there as well! I suspect the hub part of the new rotor is not as thick as the old one - I have a micrometer so I'll check that. If that is that case - what to do? Can I put washers under the studs? Seems pretty cheesy to me but if it's safe no one would ever see it.
