Many other Hondas had cable operated clutches, the clutch perches from those bikes are pretty universal. When I was choosing the clutch perch to use on my project I wanted to be able to use an aftermarket lever set from a modern bike...to be sure that I'd be able to find levers in the future.
I'm using a 90's 750 nighthawk master cylinder and a CMX450 rebel clutch perch, they use the same levers and the clutch perch has a mirror mount on it, clutch perches from sportbikes or dirtbikes won't have a mirror mount.
I searched ebay for a little while looking at different lever sets for different Honda models, most of the auctions included a little chart of all the models and years that that particular lever set would fit. With a little persistance and some detailed note-taking I was able to find just what I needed at a good price.
Also check out
www.mikesxs.net for levers, perches and switches.
I'd head over to some of the Honda chopper sites to ask around for info on minimalist switches.
