Hey all! This part number is stamped on a metal bracket on the bottom of my stock H-D Seat but im trying to figure out if this is the part # for the bracket, or seat pan, or whatever! Almost all listings for seats for sale on the web list this part number even though they are for or off of different model H-D's. The number is RDW-92/61-0067! any help would be appreciated!:what?
