Stop in for a cup of coffee

Call Mike at AMS bet he has them also give Rick@lawsons a shout, he deals with weird stuff all day long. What is the exact application?
I haven't called either of them yet.
I've talked to Rick before, and bought a couple things from AMS. Didn't think they'd have these.
Top is 1.75, lower 1.50 pretty basic radiator to engine, nothing weird.
