Thanks Dale. I also found this one that has 2 3/8" fittings: http://www.streetrodstuff.com/Products/1749/ The price is a little better. I've also read that some GM housings actually have a fitting for temp sensor in them, but have not been able to find one yet. I wish I had thought of this problem in advance. I could have had a bung put in the radiator. Live and learn. Thanks.

Check http://cantonracingproducts.com/coolant_acc/coolant_acc.html about half way down the page, item #80-116. It's a water neck spacer that fits between the intake and the water outlet housing. It has a single half-inch NPT port and two 3/8-inch NPT ports for temp senders/lines. Two of the ports would need to be plugged off and you could use a reducer bushing to accept your fan temp switch. A little pricy at $55 though. Another (albeit ugly IMO) option is a later model water inlet housing that is tapped for a sensor. Not sure what they came on originally but I've seen them.

Everything seems to work correctly. However, I did run into one small problem. The fans and temp gauge will not run off the same sender ... duh! I thought about just moving the fan sender to the heads, but 66 heads do not have a sender fitting. So what are my options? What have others done? I suppose one option would be to put the fans on a manual switch, but that would be a pain and what if you forget to turn them on. Thanks.
