Nice photo Dave. It struck a bell and I went poking in the Working Instructions for the Mk III 19-Set. Sure enough, in the 'group photo' at the back of the manual of all the Wireless Truck kit, there was the set of Mountings and they appear to be fastened together.
Just checked the spacing for the outer two holes on my Carriers, Sets No.21 and they are only 9 or 9.5 inches apart (they are starting to splay out a bit with age and I better address that soon), so for these Mountings, they seem to have spread the distance between the rubber feet to compensate for the wider load with the Carriers, Sets, No. 23 added to the mix.
Could you check one other thing while you have your Mountings handy? The 'standard' feet on my Carriers, Sets No.21 are 7/8" wide. Are the ones on your mountings the same width, or did they beef them up a bit as well to handle the extra load? I think I ran across one lone foot assembly years ago that was much fatter than any of the others I had with my 19-Set gear and I tossed it assuming it was not correct. Now I am curious to see just how dumb I might have been back then.
Cheers,
David
