they came out of a '66 F100 I had years ago. Every fuse had themNope. I do not buy that answer. I grew up working on cars that had glass fuses. Never saw anything like that in the older guys tool boxes, or being used, or in the cars. I won't rest until I figure out what they are. Unless I forget about this thread when I see something shiny.
unsure if they were on it from factory or if a previous owner put them on.
