i read an article from roundel about 3 years ago. it was about a para who had his car fixed up and had electronic clutch w/ manual gearbox installed. there was this little button on his hand control that worked as a clutch. i don't know if it'll work well for a quad though since it requires some finger functions. it's in one of the issue in 97, i'm not sure which one it was. i hope this would be some help.
