Parts Interchange for 74 Scamp

i can tell you that they are probably the same, every picture ive seen of a dart from the inside is like "hey, your dash is just like mine." i have a 1975 valiant. im gonna redo my interior, and ive been thinking about taking those wood panels out, replacing them with shaped and painted sheet metal, or maybe real wood. i want to redo the guage cluster to something a little more appealing..

but back to your topic, same, yes, interchangeable, sure.
