Smog pump delete

Anyone know where i can get a smog pump delete for a serpentine belt setup out of a 1991 suburban? It would be a bracket and idler pulley looking thing.

Have ya tried looking at a S10 4.3 serp setup? My 90 Jimmy with a 4.3 doesn't have a smog pump. It has an idler pulley that just bolts right to the alternator/smogpump bracket.
If your bracket has the hole all you should need would be the shouldered bolt and the pulley, (and probably a shorter belt).

Just take your junk air pump off,toss it away..worthless weight riding around And go to the part store,get the idler pulley,it will simply bolt to the bracket you allready have. and a new belt of corse...I just did the same thing to a 90... Easy to do...
