I don't know how tight I am getting them. After you do it a few times you just kinda get a "feel" for it. I have never had a problem before so I really don't believe it's operator error. I am currently running Mustang drums and hubs and ran them for 11,000 miles on my '74 Grabber with no problems. Dave, I am very intrested. I'll send you an email in a few minutes. Car has been sitting on a jack stand in my driveway since Friday afternoon, I really need to get it back on the road ASAP, paying for premium gas for my dad's 95 Mustang GT is killing me. Damn car gulps that premium down, but it sure is fun to drive.
