Dont know much about them but they are fiberglass and they are heavy. the drivers side has the front bolt hole is striped and cracked and there are scrathces underneath but these look realy good on my truck. Nothing els wrong with them other then the front bolt hole being messed up. Im asking $80shiped no less because they are heavy and shipping is going to cost alot. plus paypal fees and boxing it up fees. thank you. chuck. this is the best picture i have , if you are interested i will email you pictures by email. I have to take them first tho.
