Well I just ordered the rocker panels for my truck. $474 to my door. Probably going to replace them ourselves. Once we get the rockers we'll be able to see how everything goes and cut the old ones out. I'll keep you guys updated, and if we actually replace them ourselves, I'll take pics and make a thread.
Easy, just gotta take your door panel off to get to the mirror. take off old mirror, bolt up new one.
They're not superduty mirrors, they're from ebay. They have the ones I have for $150, and ones with blinkers in them for alot more.
