I would contact RAS because I would think they could replace the hardened pad with very little trouble.
Be aware though it's expensive to get the whole 9 yards done with shafts,over $500 bucks with shipping. But now I have a set of "bullet-proof" rockers that will probably outlast me

Gus

I may have one extra, let me check.....Sorry only a crane

There is a world of differnece between the early Isky and the later Cranes in those two picturs, check them both on the same head and camshaft at the retainers and then tell me which one had the most accurate and consistent ratio That is one of the reason that RAS kept so busy for so many years correcting the ratio on the cheaper ductile iron rocker arms like the Ersons and Cranes like those in that picture

The point is still: as a last resort he could use a Crane.

I sent RAS a bunch of different mixed brand ductile iron rocker last spring to have them bushed and accurized and ratio changed to 1.6, they where some Cranes, Ersons, Mopars and one Isky. I had to send them some more Cranes later to be able to finish making the one set, none of the Ersons would make the 1.6 ratio I now have two sets of RAS rebuilt and bushed rockers, one set of 1.6 and the other are 1.5

Really? Bit of an insult.

Instead, maybe provide a response that clearly articulates why they are “virtually identical” and teach me something, which should be easy, right?

Hey, if you can't see a similarity then there's nothing I can do for you!

Oh, now it is similar, not identical
