The Dodge Challenger Message Board

Could someone tell me the difference between 73 and 74 seats. Front and back. Also do these 2 years have hard backs on them?

No differences as far as I know. The interior stayed almost exactly the same through all 5 years of production

I believe the 70-71 seats are different,from the later years, I think the 70-71 have hard backs, I do know the foam bungs are avalible for 70-71, but they do not sell them for 2-3-4, If they do I would appreciate it if someone would let me know,Thanks John
