Even though the Amazon app said this would not fit my 1967 stock GTO 400 engine it fit perfectly. Fits in the valley pan beneath the intake manifold, not the valve covers.

Please excuse the grime. Just bought the car.I took this photo to show it fits in my 67 Firebird 326 stock valley pan.It's a tight fit but it should be!Oil up the grommet inside and out with oil from the dip stick. Then use the bottom handle of a hammer to press it in the valley pan. Go in a clockwise motion. Then add oil to the pcv valve and repeat with the hammer handle. Keep the valve centered and wiggle it in while applying pressure.Takes a few tries but it worked.Pcv valve was an ACdelco #19310783
