Found that both boards had a rattle on new 2013 FLHTC. Looks like rear mount has spacers cast into bracket to allow grip when snugged up but front mount just floats. I added a flat washer to take up space and snugged up...rattle gone. Now my question is where board contacts bracket when folded down, its just metal on metal. The board has holes cast in for what I suspect would be a rubber insert but none are on mine. Does anyones contact point have anything from factory? Thanks!
