I was told by Honda I couldn't buy whole passenger floorboards for the B, and that I had to build them from individual parts but I found a Powersports shop in Toledo that still sells and ships through ebay. I just used the alternate part # for the Valkyrie to find them. The stuff is out there it just takes some detective work.
