Took a look...from front to back of the bike....
2 bolts, heads to front of bike
angle iron on the bottom of the bat box
2 triangular horn mounting plates, single hole pointing down
2 spacers
2 large washers?(my suggestion)
fender
2 large washers(my suggestion)
nuts with loctite....
Note: Mine ripped holes in the fender about a year after it was new...I had to pop rivet pieces of sheet metal inside and outside of the fender to give me usable holes in the fender again, to bolt it tight. Suggestion: if your fender and holes are still in good shape, do yourself a favor and use nice large washers when you place the nuts on those bolts so they can't rip out of the thin stainless steel fender and ruin the fender... :wink:
PS...simular arrangement on the mounting plate above, that mounts on the frame plate, below the main tube....
