Note: Original rockers are now no longer available, they were either cast (2A533) or
pressed steel (2A964). They can be replaced by either a sintered steel rocker (CAM289) or
forged rocker (12G1221). It is advisable to replace in sets due to the difference in weight
when compared with the original rocker.
