I got mine thru a reputable radiator repair shop. They usually know who makes the better parts,and who doesn't. If they buy cheap junk,they get stuck eating the cost of changing it under warranty,and that's not a good thing for them. It's good business to buy the best in their case. I'd trust them long before a local parts store's opinion's.In my case,the owner had a connection and got me an NOS one in the GM box. As I recall,it was 40 bucks.
