engine build ?,lifter oil galley tube install

thanks rumble i really cant find any info on these things. one part is discontinued thru mopar and the dealer witch is the drill or the peen tool.
the how to hot rod book says very little about this topic other than part numbers and its fairly easy to install but the parts are discontinued witch lead me here.
i now must ask were or who can i get this part from.has anybody actually done this install and do you what to sell the peen kit.
