Bought rear caliper bolts for a 2010 Chevy Camaro....

Bought rear caliper bolts for a 2010 Chevy Camaro. Bolts for front and rear calipers are different, but there is only one part number on your website. I paid $10 for 4 rear bolts, and was sent front bolts. To return them, I have to pay $6 for a RMA and a return label. Not worth the trouble, and since this was the first time purchasing, dont think I'll order again. Too much competition to feel duped.
