Interesting, now that I remember, I've seen both types used. I even got the clear ones at the dealer. They had the parts diagram that showed placement so I believe they were correct. I had to shave them on the sides to make them flat after the bushing was installed.
So, which is the correct part? It could be both.
Edit: one says gearshift bushing output shaft to shift rod and is black 201 part#. The other clear one just says gearshift bushing 115 part #. Maybe a supersede condition or late vs early model. It is somewhat confusing, but the black ones are much easier to install. I wonder if they last as long. Both parts appear to go in the same place.
