Just wanting to know how to tell if the bellows are good or not? Is there a length it should be at room temp? I assume its fine, it was my dd for years w no problems to speak of. The engine will be going back in the car in a few weeks and its something I don't really want to spend more money on but I want to be right. So what do you guys think?

Haynes manual, page 13-14 says heat a pan of water to 150-160 degrees F, put your thermostat in the water for a few minutes, and overall length should be 1.81 in (46 mm). An eyeball method is to warm up the water, drop the thermostat in, and see if it expands.

Lets see a pic of the thermostat. It is obvious by the room temp position if the thermostat is good.

There is a guy on Samba selling new ones for around $100. Why bother with a 40 year old part that will fail.
