Besides the accessory attachment points, are all G3 timing covers compatible with each engine?

I have a 6.4 with the HD truck cover, which encompasses a high-mount PTO. I'm looking for a basic cover that still retains AC (lower driverside, power steering (mid-high driver side), and passenger side alternator. I think I found one but it only lists 5.7/6.1 vehicles up to 2010.

sounds like you want one from a 2009 up 5.7

New 5.7s don't have the power steering pumps, not sure which year that happened, but just be sure its not too new.

I ended up getting one for an 09-17 Challenger. Only difference is could see from the pics was the water pump face is smooth on the newer one, opposed to the older one that has a slightly sunk water path. We'll see I guess. Thanks for the input fellas.
