I just tried buying Sachs manual clutches from an ebayer from ebay.de
Although it says shipping to Europe only, he was gracious enough to agree to send to USA for only 6 Euros. I will let everyone know when my stuff arrives, but so far it has been a picture perfect ebay transaction, using Paypal for protection and easy monetary exchange.
He has his contact info there, but seems to work soley off ebay. This could end up being a nice resource for you Sachs lovers to get manual transmission stuff, and other hard to find in the USA stuff.
