2010 vs 2011 water pump?

This is all good info and deserves to be brought back from the dead.

As a side note, I wonder if the PS pulley from an earlier Hemi would work on the later PS pump delete bracket and fix the pulley mis-alignment issue and make it usable on earlier motors?

I was struggling with trying to find a remote reservoir fitting for my brother (see thread here) when he gave up and ordered the PS pump add on kit from Mopar. Looking at that pump and comparing it to an earlier pump made me think the pump was the same as a 6.1 pump (for example), which made me wonder if the only difference was the pulley. There are two different pulley part numbers, and the later one does look to be deeper, but it's all just visuals so not sure it matches up. But it does make it a possibility that Mopar only changed the pulley when the accessory belt moved out on the later motors.

But if it did, and the earlier PS pulley could be swapped onto the PS delete idler, maybe it would fix the belt alignment and make the idler work on the earlier motors?

Just an idea.
