Abstract: A double ended guide pin assembly includes a first guide pin body having a first rotation axis and a first keying surface. A second guide pin body has a second rotation axis and a second keying surface. A fastener element connects the first guide pin body to the second guide pin body such that the first and second guide pin bodies are independently rotatable on the first and second rotation axes, respectively. The first and second keying surfaces are selectively positionable at different orientations with respect to each other.
