I finally got the tail lights sorted out on the bike.
Started out with nothing to hold them.
Made a template out of cardboard and then transferred it over to a sheet of 22 gauge sheet metal (a little thin, I know, but keep watching, it gets better).
Cutting out the excess and bending it into shape:
The main section was too narrow to hold the plate, and a little thin, so I figured I would kill two birds with one stone and make up a seperate piece of 16 gauge sheet metal to hold the plate and stiffen up the bend:
The two pieces side by side:
The two pieces riveted together:
By riveting the two pieces together, the extra length needed by the outside piece of metal will not allow the two to bend back straight without serious kinks or bend in any further without serious stretching.
Test fit:
Had to cut the tail a bit for the light to clear.
And the finished section:
The plate is on just loosely in the picture. Once tightened up it will fit a bit more snuggly to the light. It's a bit closer to the tire than I wanted, so I may redo the whole process later to get it higher, but for now I'll go with it and see how it works
