Serious buyers only please. The properly tuned 307cid engine runs great and the transmission shifts nice and firm. Mobil 1 has been used in the motor for the last three years. Originally equipped with 3 speed auto, now has TH-2004R CZF unit and 3.23 posi differential. I have kept the seats covered and a sunshade up in the windshield. A pleasure to drive anywhere. Many steering, suspension, electric and electronic parts have been replaced, you name it, it's probably been changed. Easily passes NJ state emissions. Purchase comes with engine gaskets I have on hand, original ECM+PROM and Genuine GM Service Manual. All additional parts I have for the car can be purchased a-la-carte.
