you are correct, i should have been more specific. but i do believe everything to be original. but as you said, i dont want to assume, you know what the say happens when you ASSume.
i guess i was thinking the block would be easier to trace. idk, i am curious to know for both really, but rockers are the only reason i have that matters as far as fitment issues.
