They are different. ‘65-‘66 any Chrysler is what you need. I have one but it is buried somewhere. These folks sell reconditioned clocks: 1965 1966 Chrysler Clock Newport, 300, New Yorker, 300L
I don’t know if they’re still available but I bought replacements from the dealer last time I needed them. They’re the same as full-size vans, which were manufactured into the early 2000s.
It’s interesting that came off a ‘68. I assume it was a Canadian car. I had a US ‘68 New Yorker with factory cruise control and it was the newer style, on the turn signal stalk.
Rear defrost is just forced air- not heated. There is a thin duct in the center and a fan that takes in air from the interior and sends it to the duct, via a hose.
I have a black front and rear set in mint condition. I posted them for sale last fall and didn’t get a nibble. I was asking $600. What are you offering?
There was no TNT option for Imperial. There was the “dual dual” option, which gave you dual-snorkel air cleaner and dual exhaust. The engine was still rated at 350 horsepower.
