On my Cafe' bike I have the RYCA made rearset bracket - I used it for a model when building the peg mounts for my Retro Standard bike.
These footpegs will be mounted farther forward than on the Cafe' bike, as I want the bike to be more comfortable for long rides....the handlebars are also mounted in the standard riser mounts to provide a more upright seating position.
In order to allow the pegs to be more forward and lower, there will be outer plates where the pegs will have mounting points that are more forward and lower. I have not yet completed my footpeg mounts - spring/summer came and it was necessary for me to start doing yard work!
Here is a link to what I have so far:
