Engine Painting

OK I have decided to paint my engine in my 69 Dart swinger BLUE! I want to get as close to as factory original as I can. Where is the best place to purchase the paint and or brand of paint to use. Anybody got any information on this I sure would appreciate it. Also what color would the bellhousing,clutch linkage,Z bar and transmission be.I was thinking BLUE on the bellhousing,BLACK on the cluth Z bar and linkage and CASTIRON GRAY on the trans and linkage. Any suggestions!

Thanks

Bobby
