Help choosing the right gasket
The 27103 is a 3.25 by 3.5 inch thermostat gasket blank from Stant, the kind a mechanic reaches for when the original cut gasket for an older or less common housing is hard to find. Lay your thermostat housing on it, check that the opening and bolt holes line up with your engine's outlet, and trim to fit if needed. 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
Back in 1997, when almost nobody had a website, Don and Kathy were already selling car parts online. They were the very first web customer of Daniel Comp's Intelligent Network. They've since sold through eBay, Bonanza, and their own site, and kept the sales coming no matter how often the internet changed its rules.
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.
