How can I make my slant six exhaust manifold look great?

Rustoleum BBQ high temp paint works surprisingly well. Have it on my daily driver for 2 years and its just starting to show a hint of rust coming through. Best thing is you can touch it up and its virtually undetectable. It comes in flat black or silver. Spray can or quart.
I have used the expensive paints with poor results. The BBQ paint is only a few bucks.

Is that a factory cruise control?

Mike: Yes and no to your question. Factory cruise control was not available on a Duster until 1975. I retrofitted a post-1974 factory style cruise control setup into my 1974 Duster. You can read all about it in another article that I wrote entitled "Bob's Component Resto, Part 12: Factory Cruise Control". It works really well, but was a lot of work. Glad I did, though.
