Alright I have the Chevy Avalanche and the EXT is basically the same thing except caddy luxury and more power. But do you know those things that are on the bed that stretch from the bed to the top of the cab on the side? Avalanches have a cladded one and the exts have a nice smooth one. Does anyone here know what the name of these are? Also anyone know where I can buy these and the running boards and roof racks? ******************************** Thanks for any help.

try doing a global search for < avalanche escalade conversions >
there are hundreds of comapnies doing what you ask

here is a couple of finds:
