Gents, I inherited a 5-star reproducer that was missing a pad roller arm. The pivot screw had broken off, and no one before me had been able to get it out, so the theatre just ran without it. Taking up the challenge, I finally got the screw out, but now I'm faced with getting the proper replacement pad arm and roller assembly (the original is long gone).
Here's my problem. The casting around the sprocket shaft has three stanchions/bosses/webs (whatever) instead of the two found on all the other soundheads in this theatre. The third protrusion (see black arrow, 1st photo) prevents my using the pad arm listed in the parts book, as it will not allow the arm to close around the sprocket; it interferes with the pad arm at the point shown by the white arrow (2nd photo).
I'm assuming this is an older design, and the proper part I need isn't listed in the current manuals. Does anyone have any ideas on this, please?

PHOTO 2: The "normal" soundheads look like this. The "third wheel" webbing in the first soundhead interferes with the pad arm at this point.
