Here's what appears to be a Nardi knock off. Looks great to me.
70mm.. so i guess would it work with the Momo adapter just discussed.
And i assume it's safe to say that the Momo adapter will in fact bolt up to the W123 steering column?
So perhaps those two pieces are a matchup for this project. Not too bad of a budget either.
Now it would just be a matter of finding Mercedes logo cap for the wheel's center!
