I went for these:

They will fit, but they won't line up with the screw holes, so a bit of drilling will be required. It's a bit annoying as the Vintage Pros sold in the US have larger plate Wilkinsons, and the Gotohs line up perfectly. Over here, the Vintage Pros use the smaller plate Wilkinsons designed to fit Music Man basses.
