2016 5.7 lifter replacement

Well, it finally happened, the dreaded Hemi lifter tick. So, engine is apart in the Ram. Question, does anyone know where to get single replacement 5.7 rocker arms? From what I can see ( so far) the dealer will only sell complete sets with shafts? Any help appreciated. Got two that seem a little more oblonged than others.

I more commonly see the PR cup worn out than any issue with the big bore hole but I have seen that. All that said there is a newer style rocker assembly to improve oiling and ticking. The oil hole in the shaft is chamfered quite a bit in the newer ones to keep more constant pressure to the lifter and the wear surface in the rocker is larger. If I had some questionable ones I would buy the new set for both sides from the dealer... should be around $700 for all 4 assemblies.
