I have the original smog setup from my '72 Skylark that no longer is needed. I believe it is complete minus the bolts - included pulley, brackets, working pump (see pics). I cannot find comparable ones out there to get a value, so starting with $100 plus the ride. Ping me if interested.
Ajesh, noted your interest. Do you have questions? Also wanted to note the hose had been cut and will need replacing.
