1. You two quit arguing. 2. Bill, go find that chick who said your car is sexy and get laid. 3. What is the -exact- URL for the busty brit babes website? I'm a boob man -and- a brit babe man. Put the two together and I'm in heaven. That reminds me, Martin next time you come over you have to bring an extra for me. Oh BTW, I limped my car over to my welder guy to get the studs drilled out so I could get the wheel off. There wasn't much point doing it at my place anyway. He had better bits, a better drill. My disc was gouged and needed resurfacing. I needed his hydraulic press to get the old studs out and the new studs in. So....$100.00 later I'm back on the road with new brakes. I just need to do the rear ones. Thank God I checked the rear wheels. They'll come off just fine.
