yea, we had an "experience" with the AutoZoners. One night before the races, we were putting the 302 together, and needed bearings. Went down there, the guy gave us some bearings. Bought them home, wouldnt fit. Turns out they were for a c&*%y small-block. Went back down there, got another set, got home, they were way too big...they were for a big-block caddy. Went back down there, got the 3rd set, got home, they were almost, but not quite right, probably for an oldsmobile or slo-par. On the 4th trip, I looked for an old bearing, got the number off of it, and went back...this time I wasnt so nice. The guy said "that's what I got you the first time."--make a long story short, we finally got it back together...just a few hours before the races.
