Porsche Steering Wheel Fitment

[Paul Bahnstormerz]

Hi,

What steering boss would I need to fit a Porsche steering wheel to a 71 Bug, it has the later collapsible column, my options on boss are

all 911s to 1973

or

all 911s 912s and 914s from 1974 to 1989

would either of these fit, or am I looking at something else to get the wheel I want in the car.

thanks,
Paul
