rocker arms/ pushrod info needed

the cheapest repair would be heavy duty replacement stock type.
I thought those had disappeared for the SBM but looks like that is not the case. $200 for a full set of 8 left offsets, and 8 right offsets.

Right offset:
Mopar Performance Rocker Arms P4529474
& Left offset:
Mopar Performance Rocker Arms P4529475
