I'm a new ram owner and I just joined the forum and this may sound stupid but I'm looking for bed rail caps for 2016 ram big horn 5'7 bed. But for the life of me, everywhere I've looked online only shows for the 8ft. Bed and 6'4 bed. Am I missing something here, or am I just not understanding this correctly? Do they just not make them for my size? Any help would be greatly appreciated! Thanks in advance!
