Mark is right, the 757 III paint kit is all-inclusive.
But PW and RR engines mapping is different of course. See the repaint kit .psd files for details.

I'm currently looking at the American Airlines (N205UW) RR 4D folder. The files are: 57_REL_T.dds and RER_T.dds . The most noticeable difference is the tailpipe. I've attached pictures in the hope this might clarify what I am inquiring about or noticing."PW cowlings paint" was downloaded via ACE and unaltered.

It's the repainter's mistake. Delete the 57_REL_T.dds and RER_T.dds and it will be all right.
