Thermo-Quad metering rod measures

You can also watch Ebay for Thermoquad Strip kits to suit your carb. Not cheap but worthwhile

Nothing on ebay at the moment.

I found this site: tgmotorsports.net. They have two 10-203 kits, both opened and with only 2 pairs of rods in each. The 10-203 should have 6 pairs and they are asking $450 for a kit.
