Tom I have read up on your "work pictures" thread over the past several months and always enjoy seeing your work, it's very educational and thanks for taking the time to continue to post. Without trying to open up a can of worms... is it that you won't "re-sell" the chinese parts due to warranty concerns? I ask because over the past couple of years I have been purchasing aftermarket undercarriage parts from a vendor based on reduced repair costs to the customer. I always give the customer both OEM and aftermarket numbers and let them make the decision. Of course most aftermarket parts are chinese, korean, ect., but so far have not had to do any undercarriage warranty re-work (knock on wood) due to inferior replacement parts. I have however learned the hard way on aftermarket headgaskets, (without naming brands/vendors) and strongly discourage my customers from wanting to go with just to save a few bucks.
