51" long with 8.75" diameter Mopar driveshaft with 904 transmission slip yoke and small universal joint. Modified rear to accept Ford universal joint. Unsure of the exact Ford size, but the universal joint is new and fits a Ford 9" center section with the small yoke. I had it made at a drive shaft shop to fit my 1972 Duster that had a 1970 Ford Mustang 9" rear end. Hardly used. $100 plus shipping from 27028.
