New i'd seen them before Honda CB750F cam cover bolts!! and it just so happens that i have some NOS ones still in my stash, Part # 90017-425-000. I put a SS washer under the sucker and all looking good Just enough room for a strap but doesn't stick out that far, so shouldn't upset the "boss on the back". I'll take them off and add a dab of 222 loctite, just to make sure they don't vibrate loose, well they are now serving a different purpose and i don't want my gear to fall off
Or if you want longer ones try these, from a Honda GL1100 Part # 90017-371-010
