Need to move last 7 characters to new positon (not beginning)

I need to move the last 7 characters in 7,000 folders to a new position, that being 11 characters from the start of the filename. Examples:

From: gd89-04-15 The Mecca aud holtz-jaz 102457

To: gd89-04-15 102457 The Mecca aud holtz-jaz

Thanks for any help!

PROBLEM SOLVED! I was able to do a two-step Replace and Move to solve the problem.

Thanks for this great software. Any way to edit/delete posts without creating a new one?
