I used to buy from Truck Shop, and had the same problem at Pate. It seems the people answering the phones only know how to work a computer and know nothing about parts. The last time I ordered from them I got 3 items and had to send 2 back because they didn't work for me. The people on the phone assured me they would. Went to Chevy Duty because the phone people there are very knowledgeable. I've never had a problem with them.
