On my 68 Cougar the drive shaft is all messed up so I'm looking for another one. A guy locally has a 67 Fairlane that has a drive shaft that he is selling. His car is a 3 speed manual and on mine I did the AOD conversion, but I didn't have to shorten my drive shaft. Will his fit and work? If not what other drive shafts from years and makes of cars will fit?
