I don't believe this panel is available now, it is not shown in the Mini King catalog for example.
When I converted my `matic to a manual remote I made my own.
Cut a rectangular bit of 1.0mm-1.2mm sheet steel, round the corners, beat it to fit the floor shape, then spot or plug weld it in with the MIG. Cover with some paint and it'll look like a bought one.
