From the parts conversion chart, I got a Stant brand thermo from a 1983 Hoda Accord (192 or 195 degree) and it works great. Cheaper, and it has a weep hole already in it. If you do replace the thermo, order at a minimum, both o-rings before you dig into it. the large one is usually the consistancy of black bubble gum if it is old. They would be 92055 and 671 in the picture below. 92055C is the o-rings for the cooling log to the head. Murph sells a kit for these for a great price.
The big o-ring:

Also inexpensive. when you change this (quickly) you only loose a few ounces of coolant, so you don't need to drain the system down. If you want OEM, Murph carries it too.

Now, watch out for hurricane Sandy!
