OK Guys, I went crazy.... Not only did I add locks to each side of my rear rack for 2 helmets, but I also added locks to each side of my upper sissy bar, in order to lock up the expensive leathers. I have all the parts made, I am now just waiting the locks to come in to assemble all 4 on the bike...
FYI, I'm adding nylon straps (metal cable interior) and D-ring hooks to the leathers... someone will really have to want to steal them to cut them off with heavy cutters or potentially ruin the leathers by ripping them off. . Regardless, it is cool and secure. The hooks are strong enough to pull the bike over.
Plain bracket from Home Depot. Will need 2. Red lines are BENDS, Black lines are cut-offs
One I had the bracket partially formed I tried it on the bike for testing.
Once all the bends and cuts were made, I dipped the brackets in plastic. Probably didn't need to do this, but I wanted an all black look. Could use paint, etc, whatever sticks to the zinc brackets.
I made a rubber gasket/filler, and a cavity to allow the recessed lock nut
Here is the assembly. Bracket, rubber gasket held on by brass screws (nipped off to length).
Rear view of same, You can see the lock nut recessed in the rubber gasket.

Rear View. Here is why I created the rubber gasket, to cover the void between the back of the bracket and the sissy bar. you have to have a void to allow room for the lock nut. I suppose you could screw the lock directly into the sissy bar upright post, but I chose not to do that. The black rubber gasket closes the gap and makes it look more like OEM Stock. I doesn't really provide any dampening, none needed based upon the bracket design. FYI.

The straps for the luggage do not interfere based on location high on the sissy bar.

I gotta tell you, this was a royal pain in the ass... trying to fab the brackets, etc.... however, in use, I believe having the convenience of the right locks, in the right places, will make the experience more enjoyable.. Next time I ride into a town and walk around for hours, I've got a secure place for helmets and leathers for 2 riders, all keyed to the same ignition key. BTW, i did end up using 4 of the identical locks that came stock on the bike. approx $50 each from the dealer or cheaper online if you can get lucky and snag one.
As i mentioned, the mounts are strong enough to pull the bike over... However, when I bend the metal bracket I do know that that does weaken the metal, however, with no more movement/stress, I hope the bends hold up without cracking.
