Found one of these on a '74 bug engine in COlorado. It's a connection for an EGR valve. First time I've ever heard of one on a '73. Maybe that's A california engine (did '73 California engines even have them?), or maybe somebody put it on from a '74 engine, to put the engine in a '74 CA bug and pass emissions tests? Or maybe that's really a '74 bug engine (rebuilt at some point with a '73 case?).

To my (limited) knowledge, '74 bug engines were the only year to have this.
