Welcome! I found myself in a similar situation, needing to fit my older Singer 201 to a more modern cabinet! I spent lots of time fussing about it and finally talked to my DH. He went into his scrap wood supply, pulled out a 1x4 cut to the size of the base of my machine and voila!, my machine was flush with the surface of my cabinet. The fit side to side was perfect but my machine base was still shorter than the cabinet opening, so DH fashioned up a "filler" piece and it has worked out great! Hope that helps!
