I've got a flawless copy of "How to Rebuild and Modify Rochester Quadrajet Carburetors" by Cliff Ruggles that I bought when I was tuning on my 72 Skylark. After selling the car, it has just sat on a shelf in the garage. The book is in brand new condition. I paid $25 plus tax, so I'm going to offer it up for $20 or best offer plus actual shipping.
