If you have questions, or need some photos, I should be able to help some (my father is a FORD drag historian of sorts, and I also have a bunch of literature). Interesting fact, the pro stock Mavericks/Comets had Dana 60s in them and factory bench seats when delivered to make legal weight. My father also has his 73 Comet he bought new, and a 71 Maverick he bought to turn into a period correct pro stock tribute car
