Here is the problem. These bolts came up on the amazon search for my 1991 Miata. The description does not include the applicable cars, and does not include the size. Actually, it does include the size - the size of the package, which is completely useless. If the description said the diameter, length, and thread pitch, I could have gone "Gee, it looks like SAE bolts, not metric. Maybe this doesn't fit". Only after I opened the package to test fit the bolts (test failed), did i go back the package and see it said "SB FORD HEX SS THERMOSTAT HOUS". For some reason, this did not flag in amazon that it didn't fit my car. Usually it does. But the seller should have better description. If the description had said "Ford", it probably would not have come up on my search.
