Large Style Thermostat Housing

Tony's Parts sells a brand new reproduction thermostat housing. Lots of originals are heavily pitted. I got my heater hose nipples in the HELP section at my local parts store. If the HELP line doesn't have what you need, they should have something behind the counter they can look up.

I want to say that the large thermostat housings(aluminum) were used up until 1980 or so. Then they switched to the smaller steel housings. Not sure of the exact year.
