The (painted) steering wheel that is shown on the photos was the 3rd / 4th season one with the grooves in the grips.

The grooves are filled up with filler to make the 1st / 2nd season wheel from it, so it's that easy to convert it!

And as you can see, it will turn out great once it's completely finished.

 

We also can deliver the steering wheel without the opening at the front side (to mount the adaptor), then the opening will be located in the bottom of the metal tube on the back side. This way you don't need the metal cover plate at the front side anymore, this will give a much more "cleaner" look.
