Fix For Early Coil Spring Clutches.


If you click on the image opposite you will find a really good solution to a slipping early coil sprung clutch. The pre 1964 cars were fitted with these clutches.

By following the instructions given you can convert your early coil spring clutch to use the standard selection of Diaphragm springs. This is the only real solution to this problem.
