THE SERVICE manual says to look for LH and RH stamps and match accordingly
< RL RL RL
< LR LR LR but there isnt any LH or RH stamps they are a VERTICAL STAMP WITH EITHER A SLASH AT THE TOP OR BOTTOM!!!!

TOP SLASHES ARE LEFT
BOTTOM SLASHES ARE RIGHT. jus some FYI since i had to dig in a junkyard to find this out cuz the SM didnt clearify

 

Good find on the info.

 

interesting...of course for mine i was just going to cut out the small section of rust and weld a plate in...no use replacing the whole thing for a golfball sized hole in the rocker.
