After searching the web with "mixed" results...
I picked these up at my local O'Reilly Auto Parts for $4.99.

Dual contacts, 12v (rated 13v 7.5w)- Made in China, Imported to the USA by Sylvania of Ontario, Canada.

I think the '66 has 3 of these, but I only needed 1 at the moment near the passenger kick panel. This was cheaper (and faster) than ordering the multi-bulb pack from a vendor (eg. Ecklers)

Just FYI - in case you can't find them anywhere.

The OP bought the bulbs from O'Reilly's! His tip can have value too someone reading the CF. Yes, some people order some of the most common things via the internet. Not everyone lives around the corner from a well stocked parts emporium. Dennis

Any auto parts stores and even wall mart sells bulbs.

What's the C3 reference about?

Try NAPA/Car Quest or the more 'legitimate' old school parts stores next time.. KEY Auto Parts is where I go here.

Buying a card/box of ten Sylvania bulbs, from small dash bulbs to 1156/57 taillight bulbs will run you around .40-.60/bulb.

If you live close to a shop that repairs big trucks that's anther good place to buy bulbs and grease and oils.
