I am trying to find out what the correct bolts or screws are (and look like) that hold the fan shroud to the 26" radiator in a 1971 Charger R/T. The speed nuts that are on the original radiator are very small and I am not able to figure out what thread pitch they are (not 8-32) Here are a couple of pictures of the nuts.... Any help would be greatly appreciated. Thanks in advance.

Take the fastener to a hardware store that has the test threaders by the bins and see if you can determine it that way. Just a thought.

That may help to find out the thread pitch but I also need to know what the "correct" head looks like. Thanks

Have you tried this guy, looks like he may have or know exactly what you are looking for.
