I made my own saddlebag supports. (wish I woulda got pics of the process, but I didn't
There's pics of the finished parts HERE
I just bent them by hand & vise (they aren't both the exact same, but close enough)
Got some steel angle that I ground and drilled to fit at the top shock bolt and helmet lock bracket (no longer have helmet lock)
Welded everything together and took them to work to have satin black powdercoated.
If ya have any specific questions, just ask.
And there's been several here that have made floorboards. Some from metal, as well as wood.
They are kinda easy in that the rubber pads on the stock pegs can be unbolted, then something made to fit right on top of the peg itself.
