Here is my project so far. Grabbed a piece of scrap steel and clamped it to a metal work bench. Hammered a length at 90 degrees, then clamped at the bend to an old bed frame section and hammered the length around it. (As shown in last picture) Used an angle grinder to open the edge for the tabs to go through and slightly widened them with a flathead screwdriver. Fits nicely on back bracket. Tomorrow I will source 3 screws to the listed specification, drill three hole in the mounting bracket and put this machine in its final resting place. Thanks for the help!!
