Proper paint colors for BB512i

I have a new (to me) 84 Boxer with some paint areas that need to be redone (and a few other questions). For example: the spoiler at the rear edge of the roof and the engine-lid "carb covers" have been painted red when they should be a satin black (as I recall, matching the black engine lid louvers). Also, the intake manifold plenums and runners should be a gray wrinkle finish, and need some touch ups. Anyone know the proper paint colors to get a good "factory" match? Also, what color were the brake calipers from the factory? Was the skinny spare held in place by a leather strap, or just gravity?
