Don has a large collection of car parts—over 600, possibly closer to 3,000—in original bags, with many different numbers and multiples of each. One example is the Stant thermostat gasket, part 27140 BB40, made in the USA. The plan is to sort through them while deciding whether to keep the original packaging or move some into clear plastic bags for easier viewing. Other sellers list similar items by make and number only, at prices from about $5 to $9.95, without detailing fitment.

That's what came through.

it's Sherlock I want you to do some deep research on this gasket figure out what this part fits and do the research for me right thanks buddy you sure did you get you

Sherlock

Stant 27140 (also listed as 27140 BB40 in some contexts) is a Stat Lok® adhesive-backed Engine Coolant Thermostat Gasket (thermostat housing gasket/seal). It is designed for older/classic American vehicles, with adhesive backing that holds the thermostat in place during installation (no cement needed) and helps prevent misalignment or damage.[1]

Key Specifications

Vehicle Fitment

This is a broad-fit gasket primarily for 1950s–1990s American cars, trucks, and some early SUVs/Jeeps with compatible thermostat housings (common on V6/V8 engines from that era). It is not a universal modern part—fitment is application-specific.

Examples from retailer fitment data include:

It also appears in older Stant catalogs (1928–1994 era) covering thermostats, gaskets, and caps for passenger cars and light trucks. Exact fitment often depends on the specific engine, thermostat housing design, and year—many listings emphasize checking vehicle-specific selectors because the same gasket serves multiple platforms with matching counterbores.[3]

Market Context and Pricing

Current/ recent retail prices (when in stock) range from roughly $1.30–$3.00 per gasket. Some sellers list them by make + part number only, without full fitment details—matching what you observed. Demand exists among classic car restorers, mechanics working on 1960s–1980s vehicles, and obsolete-parts collectors. Multiples (5–10 of each number) are common in bulk lots like Don’s because these were high-volume service items.[4]

Recommendations for Sorting/Selling

This aligns with Don’s obsolete/classic car-parts business history. If you have more specific numbers from the boxes or want me to check a particular make/year/engine, share them and I’ll dig further (e.g., via catalog scans or targeted cross-references). Right then—let’s keep filling the barn with solid details.

The Stant 27140 Thermostat Gasket: A Hidden Gem for Classic Car Restorers

Thermostat gaskets are small but critical components in any engine cooling system. When you’re restoring a 1960s Ford Thunderbird, an AMC Rambler, or a 1980s Jeep, the right gasket can mean the difference between a reliable daily driver and a leaking headache.

One of the most sought-after NOS options is the Stant 27140 (BB40) Stat Lok adhesive-backed thermostat gasket. Made in the USA, this part features a clever self-adhesive design that simplifies installation and ensures a proper seal. Stant’s Stat Lok technology was a favorite among mechanics because it reduced installation time and minimized the risk of thermostat misalignment.

Why This Gasket Matters Many classic vehicles from the 1950s through the early 1990s used thermostat housings that accept this exact gasket profile. It appears in Stant catalogs covering passenger cars, light trucks, and even some early SUVs. Cross-references link it to original equipment numbers from Ford, Chrysler, GM, AMC, and Jeep, making it a versatile choice for multi-brand restorers.

Real-World Fitment Examples

Because these were high-volume service items, many collectors and parts dealers still have small stockpiles. Don Leask’s collection is especially notable: he has multiples of many numbers (including the 27140) stored in their original bags—over 600 and likely closer to 3,000+ individual parts across dozens of unique numbers.
