Uh Oh !! Bad knocking !!

Whattaya think, can I reuse that pushrod?? Assuming it's not bent. Can you buy just one pushrod??

What are all those numbers on the various rockers? I know there are lefts and rights, but do the numbers have any meaning? Can I just purchase and install any ol' stamped rocker?? I remember MOPAR Action had an article on stamped rockers a couple of years ago...
