Here are the ones I did last year. Mine only fit with the T-100 sprocket cover but are very close to yours. Mine are 3/8 inch chrome plated steel. They are much more comfortable for long legged passengers and offer another place for me to put my feet on long trips. I don't use them much now that I have the floorboards but I still like them much better than stock. This is what the right side looks like. There is a little condensation on the chrome due to a cold garage and a hot humid day out. I have the diagram I gave the machine shop if anyone is interested.
