Tipsy,
I have a dual seat, I don't have any rear footpegs, I have the tailsection with the tailight still in it but it does have a crack in it (I don't understand why this would be required as it stays on the bike when the conversion is done, or at least it did on mine). Not sure what you mean by frames for each side, if you are talking about the big alloy bit that the footpegs are mounted on, I have the ones from my project bike which still have the rear mounts on them. If yours no longer have the rear mounts I'd be happy to swap them as I will be cutting them down for the project bike. I only have one mirror but no mirror cover.
Let me know if you need anything.
