Richard, here's a picture of mine (all original parts) with some approximate measurements to both the flat part of the top cowl bar as well as to the top of the interior dash panel. Hard to tell from your picture if the interior panel is in place or not.

Also took some measurements of the windshield posts themselves, which as far as I can see, would be the only thing that could affect where the frame itself is positioned (assuming the stud is in the correct place on the frame). From the center of the windshield stud hole to the center of the top mounting hole on the post I get about 13-1/8".

I don't have any rubber to try out, but from memory would guess that the rubber strip should just clear the flat part of the cross bar. Let us know how you make out.
