Default Smog pump

The smog pump in my 85 started making a lot of noise. Since putting on headers it is no longer really being used it is there to pass the visual inspection. I was going to look through the wrecking yards for another pump. What other cars used this pump?

Default Pump

That pump is corvette only because of the mounting and the inlet/outlet locations.
There is a kit to get rid of the pump.
if you are handy, you can make your own kit. Check mid america and zips corvette, ecklers for pics.
use a pulley from a 2001 tahoe idler bracket. Use aluminum 1/2” thick and 1” wide, buy 2 ft.
also aluminum 1” dowel cut to the right length. Drill and tap for bolts.
also thick wall alum tube for spacers. You can also use steel
