I have 3 nos ford script #1BA8592A-2 looks to be later ford [cant remember where I got them] pick up ,Hialeah fla
The key to this is the "1BA" at the beginning of the part number. I don't know what year that's for, but my '49 Ford has an "8BA" engine in it.
For what it's worth.....
They look like the ones for '49-'53 Ford & Mercury flathead V-8. They have the recess in them for the thermostat.
