Does anyone have a complete "TACH" drive assembly that might be for sale? This is the one that bolt to the front of the inner primary case. A10 SR 1960- 1963

Well, the speedo drive on the A10 always comes off the gearbox.
The takeoff on the late A10 TIMING cover drives the tachometer. and this is 3:1 reverse and difficult to find.
You could transfer the speedo drive to the rear wheel using later parts but a lot of trouble. It would however fix the oil leak from the drive cable.
Best of luck, Pat A.
