Mystery SB Valve Covers & Rubber Gaskets

The one with the PCV grommet is between 67-69....

Interesting combo... You can run the rubber grommet PCV cover on pass side, then use stove pipe cover for driver's side with oil breather.... Slick...

Exactly how I had them.These are nice units on the cheap for a modded setup.
Having wiring harness holders on drivers side also worked great for my temperature gauge probe and electric fan wiring. Good clean look.
