1970 up valve cover breathers, 1 nipple, 2 nipples, 3 nipples.

I put this image together a while back because some sellers were trying to to mislead potential buyers with the wrong information on sites like Ebay & others.

These are the facts for 1970 cars & the only cars that ever used a 2 nipple breather originally are the 1970 /6 cars with N95;
