Anyone here know where a guy can get a set of rail caps that fit the "new" short box? ( 5 1/2 footer ) i would prefer diamond plate if anyone knows of a web-site. All I ever find is caps for the standard and long box. Also, can a factory stereo in an '06 SLE Crew power the BOSE speakers that come with the premium sound package, or do I need an after-market head unit?
