If you search on the web or eBay look for 6CXY8 or 3008BG. Both numbers will get you the knob.
On my 31 Open the deck was fitted with an aluminum block in the fiberglass that was drilled and tapped to 5/16-18. Unfortunately Tiara used a poor choice of aluminum that corroded big time and caused the fiberglass deck to bulge up.
If you drill into the deck you MUST seal the hole against water getting to the balsa core.
