On the sunroofs, the ones for Challengers and B-bodies will fit, Barracudas are smaller. The A body sunroof panels are smaller, and the C-bodies larger. Since ASC did the sunroofs for Ford as well, I have heard that the sunroofs from some Fords will fit and work in Challengers and B-bodies.
AC was not available in the T/As or AARs.
T/Ake care,
