2010 vs 2011 water pump?

Just to update my own thread, as this one went unanswered. The 2011 water pump is about a half inch longer (off the block)than the 2010. For anyone that stumbles upon this in the future. I Speculate that when these cars went electric power steering, chrysler revised the north south spacing on the accessory drive. I see this Change documented nowhere on here so I wanted to update it.
What you will find if you look up the accessory drive components is that although these engines changed reluctors and went vvt in 09, the 09/10 harmonic balancer, alternator, and water pump are not blind bolt ons to just any VVT 5.7. So for you fellas looking to do swaps and retain oem style accessories, keep this in mind. Everything changes in 2011 (to more pricey items to replace of course) this is why the electric ps delete pulley does not align with the older drive, and needs modified on pre 11 engines. The TC appears to have some 09/10 overlap. I'm guesing more due to late 6.1 production. But the alternator, WP, balancer, and that PS delete pulley are 2011 and up.
The idler and tensioner appear to be unchanged as the attachment points on the water pump are spaced outward compared to the 09/10.
Hope this helps someone in the future knowing replacement and dress components aren't just as simple as "09 and up"
