dual manifold BOLT size for sniffer tube port ???

[scorpio71 at charter.net (Jeff)]

I was just filling an existing hole, I didn't have to tap it. I thought I
remembered it being for the o2 sensor, but now that I think about it... it
may have been sticking out the side. It wasn't a pretty fix... but at least
you will know the thread pitch if it fits.  Jeff
