The 67 should be a squared off brass elbow with threads for the pcv valve to screw into. That fittimg looks like what would be in the manifold for a manual transmission car with power brakes. This is assuming the normal open pcv system for 67. I don know about california emissions equipped vehicles.This is how my 68 looked when I pulled it years ago. Not sure if differences in the years.
Oh, no, yours is correct for a 68. 67 used a different system with the closed script valve covers still. I was just saying that the fitting looked like the manifold take off used in 67 for manual trans power brakes. An auto trans would have another branch coming out the other side for the modulator line.Mine's manual trans and and manual brakes. Could have been changed over the years.
Probably the same as the pcv valve as I see pics of them screwed directly into the carb all the time. I would think you could get one at loews or home depot. Not the exact correct part but close looking and brass.Tom, What thread size is that elbow? I can look through my boxes.
