I had to order a replacement part for my old Suburban. The repair shop recommended your site to order the parts. The criss-cross of manufacturer and oem part numbers complicated the order, but with the assistance of the vehicle compatibility checking, i was able to order the correct part, and with a great deal more confidence. I was really happy that the checker worked for 1994 model year. Great job, good site feature that will bring me back for my next order.
