Does anybody have the Cummins part number for the rocker arms that DO NOT have the plastic retainers on the tappets to hold them to the rocker arm. I have one that is broke on my 05 and would like to replace them with rocker arms that do not have the plastic piece. I have heard that the ones from the 2nd gens will fit and don't have the plastic pieces. Is this true??
