I think they're the same. I hope!
Make sure you use the reamer Vans recommends. 0.311" I think.
I buffed off the burrs inside the towers and the gear then applied a light lube before sliding them in. They fit pretty snug.
If memory serves me right, there is a left and right but it was about 8 years ago when I installed them and my memory is not as reliable as it used to be.
