I am still trying to get the smog pump, diverter valve, etc so I can get thru DMV...seems 1981 is a one year only system. What would be the best way to find out the most commonly used air pump system (seems there have been LOTS of set-ups used) so I could convert the whole system to one that can be more easily located and purchased for the future (as I hope to have this car for a long time)? thanx
Steve,
Some one posted the ACDelco web site that had cross-referencing of parts.
You look up the part # - then search for all the vehicles that used it. You
might be able to find some of your components like this.
