I ordered 20 cam cap bolts. It took over a month to get them in and they were wrong! When I attempted to return them YOUR PARTS MANAGER THOUGHT IT WAS FUNNY!! THEN HE SHOWS ME THAT THERE ARE TWO DIFFERENT TYPES OF BOLTS, AND HE ORDERED THE WRONG ONES! I left without returning the wrong bolts because I was so mad that had I lingered, someone was going to get whacked
