Early A-body parts pricing
i have installed a 1975 Dodge Dart drivers side exhaust manifold on my 1965 Barracuda. it fits. your fitment may vary. i have yet to try and run exhaust pipes to it, though. we will see how that works out.
the DURANGO magnum MANIFOLDS would NOT fit!!! Dang it!

i called a couple of JYs that had the exhaust manifolds listed for my car, asked the right questions and came up with the centerlink for $40 (shipped) from one of them! you can use the Passenger side exhaust manifold off nearly any thing. if the 64-66 is the one you want, most JYs are in the $75-90 range shipped.
the headlight switch IS still produced. got mine from CarQuest. Any auto parts store worth a darn will have it. i had to use a dimmer switch off a Ford truck, just turned the wire connector over and voila! but i digress.
good luck.
