Incidently, I'm a little confused with your description: 'Spicer' refers to the U.S. manufacturer of the entire half-shaft, which consists of a pair of u-joints made by Spicer or someone else, yokes for the u-joints, a splined slip-joint in the middle, and adapters for each end (made by Spicer) to fit up to inner & outer Pantera stub-axles. To my knowlege, there is no part of any half-shaft assembly referred to as a 'spicer'. Are you speaking of the greasable splined center slip-joint? Stock Pantera half-shafts made in Italy also contain these as do British-made TVR-Griffeth halfshafts (for example).
