Up for sale is an original Trans Control Spark solenoid (TCS) that was used on 350 and 455 motors. This was a spare one we had for our 71 Buick Skylark GS 350 convertible but should fit other cars as well. This part was mounted on the one bolt for the carburetor and was hooked up to a vacuum line. This part worked and was removed from the car for one that was correctly plated. This one that is for sale has been painted with the gold cad system paint. Stamped on the face of the piece is DR1114430 which I am assuming is the part number. Price is $50. Part is located in Northern NJ. The only thing I see wrong with this piece is that the rubber seal where the electrical contacts come through the housing had some rubber starting to dry rot so we put some black RTV silicone on it to keep the moisture out from the solenoid. Any questions, please contact me through PM or email. Thanks, Brian
