This is my Plymouth GTX: This is my 1970 Plymouth GTX. It is one of 328 440+6 Bbl automatic GTX's built by the factory in 1970. I've owned the car for a couple of years now. Since I got the car, I've converted it back to factory original, replacing the aftermarket parts, rebuilding the engine and transmission. Restored the interior. Replaced the wheels and tires with chrome Ralleys and Goodyear Polyglas GT's . Installed the correct exhaust system. It's a ongoing project.
