    I was sent the wrong wrist pin bearing and this seller had no issue helping me over the phone figure out if it was an issue on my end or his. Ended up being a packaging error and he apologized and instantly issued a refund! Even though I was sent the wrong part I will be doing more business with AZ Quad parts because of how fast and easy they are! Seriously good guys over there.
