Driveshaft Questions

[Crewchief]

I have a lifted 1996 F-250 with a need of driveshafts with double cardan joints. The first question is what years did Ford supply their F-350's with double cardan joint front driveshafts? I am thinking this should be a bolt in piece. Second what diameter is the rear driveshaft on the later Broncos? I need double cardan joints for both a 3" tube (rear) and a 2 3/4" tube (front). Thanks in advance!!
