Thermostats/Flowkooler
The Flowkooler/Robert Shaw thermostats that have the soldered ring to fit the older housings may be the reason some of us have had a problem with leaking housings.
Look closely at the picture between the old stat on the right vs the new on the left. The outside of the center ring is almost 1/8" larger than the one on the right. It doesn't want to settle into the housing. So, looks like I am buying another Flashpower housing. Previously, I had gotten away with this with a Real Gasket silicone gasket, but hadn't noticed this until now. My Flowkooler water pump on the '69 blew the Real Gasket out. The '72 is a stock pump, but I am going to get another housing anyway.
Just throwing this out there.
