Help choosing the right gasket
The 27153 is a Stant Stat Lok thermostat gasket. It replaces the older Stant number 25153. "Stat Lok" means it has an adhesive backing that holds the thermostat centered in its seat while you bolt the housing down, so there's no gasket cement, no thermostat falling out, and less risk of cracking the outlet flange. Stant cut a different gasket for each housing design, and Don stocks several of them, so check which number your car calls for.
Before you order, match three things: your year, your model, and your engine. Catalogs list fitment by vehicle, but some engines had more than one thermostat housing design over the years. If your old gasket is still in hand, compare its shape and bolt holes, or just ask Don and Kathy. They'll help you sort it out.
Real people behind the parts
Don was born in 1936 and grew up on a Saskatchewan farm, four miles from a town of about 150 people. As a young man he drove trucks through deep snow in Canada's Northwest Territories, hauling dynamite to seismic crews. Kathy grew up in South Dakota, blizzards and all. Together they've spent close to three decades helping people keep old cars on the road.
These gaskets come from Don's own shelves, in original Stant packaging.
Price is $9.95 plus shipping.
Don and Kathy offer a fair deal for this. Buying for a club, a shop, or a whole fleet of project cars? Even better.
