A one-piece, exposed type, tubular driveshaft is used on all models. The driveshaft has two cross and roller universal joints and a splined slip joint. The cross and roller universal joints may be of two types. The first is the Cleveland type which uses external snaprings for trunnion retention. The second is the Saginaw design in which the trunnions are retained by a nylon material which is injected into a groove in the yoke. A third type of driveshaft, introduced in 1971, employs a constant-velocity joint at the axle end. It should be noted that this last type of joint is not serviceable.
