Shifting margins of odd-numbered pages
I have a book that I uploaded to CreateSpace nearly a decade ago. We transfered it over to KDP Print, and it's been for sale with no problems.
Realized we had a newer PDF that hadn't been uploaded, so I need to update.
Unfortunately, KDP shows that the right-hand margin on about a dozen odd-numbered pages is now about a tenth of an millimeter over their outer margin limit:

This was clearly a shift between the CS and KDP specs.
I could easily shift the pages in toward the gutter in InDesign. Unfortunately, I don't have the InDesign file for the latest changes (which were made years ago).
So what I'd like to do is use Acrobat to shift the print area toward the gutter.
I tried to use the Crop tool — and I can subtract from the left-hand margin of odd-numbered pages easily. But I can't figure out how to add to the right-hand margin, so I end up with a page that's no longer the right size.
Help?
