108" and 111" A-bodies got the same basic length strut rods for the same model year.
I've heard the 73-76 K-frame strut rods are slightly different length. I have not confirmed this though. So maybe they are being mixed with the strut rods from the old front end? You can just use the strut rods off the old 68 Dart front end if they both match. I just measured some I have at 16 13/16" seating edge to seating edge. I think those were 73-76's. They worked fine in my 68 Barracuda with 73-76 K-member for 12 or so years.
I bet one of the strut rod was replaced with a B-body strut rod. They look identical. I made this mistake once and the alignment guy spotted it. One wheel was set back more than the other.
