a better question would be did ford use any different serpentine pullies on certain vehicles that would be favorable to snag while in a junk yard?

go-fast parts for cheap FTW

I don't think it matters
In regards to the j/y Ford pullies:
Some u/d pullies are actually Ford parts re-badged

I've not seen a list of actual Ford pully sizes for ref.
That would be handy

summit aluminum u/d's are cheap and the quality is great, and they're really lightweight
