I've currently got an IVA friendly steering wheel that's slightly smaller than the moon.

Can anyone recommend a smaller steering wheel, around 300mm that will fit the Sierra column? I'm trying to work out pedal and dash layout but can't get my knees past the 380mm standard Sierra Ferris wheel. I'd like to make the dash to suit a smaller wheel, but keep the big one for the iva.

Momo wheels come with a boss to fit the sierra column and are IVA-ok. I imagine others do as well.
