Freewai.com seems to be an excellent source for Chery engine parts. The shipping can get expensive, but it may still be an alternative if the stateside vendors are telling you they don't have it, can't get it, or it will take a long time.
The day after I ordered a Chinese guy called me and spoke good English. He called to inform me the FedEx wouldn't accept my package and that he recommended Hong Kong Post. It was no extra charge. I sincerely believe they really just wanted me to get my part ASAP and felt bad that FedEx declined it. Even with the confusion the part arrived in 5 business days. The part was exactly what I ordered and needed.
