Recall that pushrods come in two stock lengths:
- short-deck engines (A10, A12, A12A, and late A13)
- tall-deck engines (1974 A13, all A14 and A15)
- Datrats - Custom pushrods made to length from VW pushrods and using the A-series cup. They sit the turned down cup shaft on a ledge in the alloy. Custom made to your length and cheap.
