The TD 160 should have a metal "doughnut" around the spindle, which you pull out and turn upside to use as the 45 adapter. If your table is missing this piece, eBay is your best bet for a replacement.
Insert for 45 RPM singles
Does anyone know where I can buy an insert to fit over the spindle of my Thorens TD 160 to accommodate the doughnut hole in single 45 RPM records?
