Stant 27135 Thermostat Gasket for Ford Custom (1964–1965)

Ford built cars, pickups, and vans for every kind of driver, and many Ford engine families stayed in production for years, which is why one small gasket can show up across a long list of models. On the Ford side, the catalogs list the Stant 27135 for 9 models from 1963 to 1965.

This page is for one model only: the Ford Custom. It isn't a wall of every car ever made, just yours.

Help choosing the right gasket

The 27135 is a Stant Stat Lok thermostat gasket. The catalogs list its hole diameter at 1.81 inches, which is a handy check against the old gasket in your hand. "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

In their early web days, Don and Kathy built separate "garages" online, one for Mustangs, one for Chevettes, and one for Corvettes, so that every owner could find their own corner. These pages carry on that idea: every model gets its own page.

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.
