As above are all paddle shifts designed for sierra columns?

I have a bmw 3 series steering column and wondered if anyone does a universal version?

cheers

Made a couple for competition cars

Paddles on OMS
OMS Single seater hillclimb car

Paddles on OMS2
With wheel fitted

Paddles on Radical
Radical Clubsport

This model uses 255mm D shaped wheel but easy enough to get other sizes cut.
