Great info. Interesting that chart show s the 103 & 1281 as a ThreeBond as well but AISIN offers those under the same part numbers. The OE Toyota 103 & 1281 boxes say "Supplied by ThreeBond International" and the AISIN boxes say "Distributed by AISIN" so suspect ThreeBond is the manufacture for the US market and either supplies it to AISIN or AISIN makes it for other market? The OEM Toyota ThreeBond 1281 actually says "Made in Japan" where the OME Toyota ThreeBond 103 is not indicate, the 103 AISIN shows as "Made in the USA, perhaps by ThreeBond

. Interesting... most likely several sources for the same product.
Now, we have a 1184 "OEM Formula" offered by AISIN that is designed for Low & High Temp Coolant, it's listed as a "Semi-Drying Liquid Gasket". I've not found an OEM Toyota cross-reference but I'v not looked deep either. It's made in Thailand.
