I think the mk 4 is one of the ones that fits the splines. The thing with Vanagon & Eurovan steering wheels is they're bigger in diameter though. If you like to rest your arms on the arm rests while steering you won't be able to do that as easily with a smaller diameter wheel. That was a major factor for me. I ended up spending $400 on a Projectzwo leather wheel for my Vanagon when I changed it out
