How do you put oil in it??? The hole in the center is for the PCV valve. My '74 318 has the VC you show on the driver's side and the passenger side has a hole for the cc breather near the firewall end and a hole for a oil twist cap at the front. Bone stock and never been removed. OTH, the MP chrome covers I will be putting on are in deed identical. I will have to cut a second hole in one for the breather. Srry, I don't have any pics but it looks like you have three lefts (Driver's sides) Still want to know how you get oil through that little grommet hole...
