I have a 1983 Bahner Jet Boat with a 454 Chevrolet engine and a Berkley 5 stage pump. I am trying to find a part number or any info for the U-joints between the engine and pump. I have ordered replacements online and they are not the right ones. I would like to get info about them and cross-referance them to get a spicer that would work. I am almost finished my boat, and any info would be greatly appriciated!
