Hi Rudi,
if you can not find your part from the club
http://www.amoc-parts.com/store/comersu ... oducts.asp (is it 040418?) or
http://www.amcclassicspares.com/ I have had good results from
http://www.gearcutting.co.nz/page.php?id=1, when I had dealings with them (a few of them certainly rode older bikes).

As your gearbox is an AMC one the Norton dealers will also be able to help with some of the parts:

There is a nice new set of twin pipes to go on the bike, and a rebuilt magneto with new wingdings, I had to replace the layshaft in the gearbox as it was bent and the clutch has new rubbers in the center hub + new plates, the last steel plate I have replaced with a heavy 3mm plate, and the outer pressure plate was from a Triumph, I got the proper AMC one now.
One the new layshaft arrives, I will put the gearbox together and fir that to the engine plates and drop that into the frame in one go as they are bolted to the engine now.
