Ijust finished the removal of the air pump on my wife's '95 LT1. I used the mid '80's Volvo oil pan plugs in my late '95 manifolds. I took out both the fittings because they were easy to remove. The threads are 3/4 x 16 I used pbblaster for a cuple of months before takinf it apartand they came right out. I have no CEL and the car runs great and looks better when the hood is up. The hardest part was getting the passenger side air tube out. It's tight on that side.
