Strange Part On Footboard

I have Triumph footboards on my '05 America. If you check the parts diagram for these, look at: part #10, spacer, M6, Hex x 18. This is a 3/4-inch long hexagonal threaded sleeve that extends downward form the front of each board. What ever might these be intended for ???? link to parts diagram: https://triumphparts.englemotors.co...MI3dGol_jX4AIVFnZeCh2sbQGTEAQYBSABEgIKAPD_BwE

 

I know, they are an attaching point for 'curb finders' ! You know, those long thin coil spring gadgets that attach near the front of your lake pipes on your '50's cruiser !!!
