You need a "good" auto parts store counter guy. Find a store near you where at least one counterman knows how to use a parts catalog, and can use dial vernier calipers. The U-joint you need is available, it will take a seasoned veteran counterman to properly identify it, then special order it. The typical computer-nerd behind the counter cannot help you. The parts store computers are not programmed to find hi-brid, or unusual parts.
