Well Roger, it's taken me two days to get the image into the computer, but unless I'm missing something I think this is what you’re asking about.
The illustration is of a '54 with two mounting points, however the ’50 should be about the same but with one center mounting point. It is out of the Factory Assembly Manual, sec.11, sheet 2.11 for a 3100 & 3600 series. There were two 3/8” struts bolted at the top to each side of the core support and at the bottom they bolt through a doubler on the lower baffle. Mine (‘50, 3604) has a rubber cushion on either side of the cross member and body shims as required.
