Like I said, Jeff ... unless you lived here and saw those ugly things all the time, you'd probably never know it. Yes, it mounts below and slightly outboard of the alternator. The second belt on the PS pulley drives the A.I.R. pump.
The '67 manifolds all have those ports, leading me to believe that Pontiac expected to have to add the A.I.R. pump to all of the '67 Sprints.
The add-on smog equipment is relatively easy to find locally. Most of the collectors such as yourself almost never see them.
