Ken, you can get a complete Generator with tach drive here or I'm sure you can get the parts you need from them also. I have also seen the Tach drives on Ebay.

As for the Tach drive cable I usually get a speedometer cable (Balkamp 615-1604) of the right length at NAPA. They have the correct ends and are ready to install on the 540 and 560 out of the box. On the 550 and 570 you need to cut about 1 1/2 in. off the cable drive end and crimp on the proper drive for them, NAPA has the drive ends also.
