GFF you couldn't be more correct about the rear footpegs, and the front for that matter. But the rear ones do look like they were off a 75cc trail bike from the 70's.
Too bad you have already chromed your rear brackets. I hack sawed off the two mounting plates from the bracket drilled a hole, 7/16" I think, and bolted on a set of Kuryakyn MAGNUM clevises. These only take Harley pegs but the Kury adapters are only $20 and you can fit any of the Kury peg range and lean the pegs back so they run parallel with the rear guard. I have the Mini pilots on but will make a set of stainless O ring pegs to match the front.
Here are a couple of pictures, I know how every body just loves them pictures ...
This method is relatively easy for any home handy man with a drill, hacksaw and a file.
Hope this helps gives a few new comers some ideas.
Cheers
