Part of why it's outdated is it was Versailles (and Granada/Monarch option). Didn't make a zillion Versailles, it was a rare Granada/Monarch option and these cars were definitely not sports cars!
JMO use it if you want! If when I update my 68 rear axle it'll be higher numeric ratio (like 3.25:1) and traction loc (or whatever Ford name). I have factory front disc and no need for rear disc.
