I purchased the metal piece off eBay, was for a Harley. They had one with a 90, and one with a 100 degree angle. I got the one that was straightest vertically, then had to hammer down the bend so it would fit into the owners manual tray in the original pillion pad.
Then I had to figure out how to secure it in place. I decided to use a pop rivit with a washer up front, as I didn't want to modify the original p-pad any more than nesseccary.
Then I came up with the spacer washers(cut from 1/4'' or 3/16'' aluminum stock), and found some bolts,washers, lock washers to secure the rear.
I'm thinking of making a brass block off plate to cover up the view from the rear, but I probably won't, as I only put it on when momma goes, and I have to put the ****** fender back on.
Also forgot to mention, the rear spacers are only mounted to the metal piece, not to the p-pad, as again, I didn't want to modify the original pad. It is secured by being an extremely tight fit only. The front pop rivit is the only thing really mechanically securing it in place. I couldn't even pull it out without a good deal of force before the pop rivit was added.
You may want something more mechanically secure. I guess it depends how much you treasure your cargo!
