Rack/sissy bar side plates

Has anyone here fitted a rack and/or sissy bar using the side plates from a different make. As long as they're the right general size, I can redrill the mounting holes and adapt to my Givi plate. I don't have the tooling to fabricate plates from scratch. I do have access to a m/c salvage yard that has a lot of sissy bar hardware, just very little Triumph stuff.

Always interested in innovations and ideas.

I have a set of side covers and side brackets powder coated satin black but I do not have a spare sissy bar. PM me if you want to work something out.
