Has anybody taken apart a TT Industries AMC style gearbox? If so could you please post some pictures. Does it have a selector drum (Japanese style) instead of the AMC flat disc? Is the gear change mechanism the same as the stock Norton gearbox? Is the kickstart arrangement the same as the stock Norton? I assume these parts are all beefed up as is the rest of the gearbox & no stock AMC parts are used? Mine is a 5 speed XHD with no kickstart. I was originally going to use it on my race bike, but have now decided to put it on a street bike. I know they make a kickstart version so hopefully I can get the relevant parts to convert it.
