I don't have the part numbers handy right now. I just ordered the stock saddlebag guards for an electra glide standard, or a road king standard, (they are the same part numbers). You need the crashbars thamselves as well as the under bag supports that hook into them. I'll try to get some part numbers for you this evening.
As far as interference for the passenger, that depends on how tall the passenger is, the height of the passenger seat and the position of the passenger floorboards. My wife is 5'4" and doesn't have any problem with them, that is with the floorboards in the lowest position and a sundowner road king classic seat. [smiley=stooge_moe.gif]
