Hey guys, I was wondering if anyone on here has seen or bought the GM ground effect kit for the NBS truck pictured below? I'm wondering what the installation and price would entail, whether it'd be worth it to get it from the dealer (I checked on gmaccessories.net and gmpartdirect.com and neither seem to list this as an accessory, yet.) or maybe try to get a kit from an aftermarket company like Street-scene. Also, if you've seen/have this, what style is the truck? I have a Reg Cab 6.5ft box and Im not sure if this will/is just for Crew Cab.

Thanks
