The 1969 Buick Riviera could be equipped with a positraction rear axle, which was an optional feature at the time. Positraction, or limited-slip differential, helps provide better traction by distributing power to both rear wheels, especially during slippery conditions. If a specific vehicle has this feature, it would typically be indicated on the build sheet or by examining the rear axle assembly.

Only if it was special ordered. Just jack up the back of the car from the diff. just to get the wheels of the ground. Spin one wheel, and if the other goes in the same direction, then you have posi. If not, then limited slip.
