I know you are looking at breakers for a wheel, but according to ETK CD the wheel is described as Sports Steering Wheel Airbag 2, and is listed at 385mm - that must be diameter.
The wheel has part number 32 34 1 162 097
There may be a few more little parts needed with it........
I have one on my 1995 6 speed. The wheel is still not as nice as the non-airbag 3 spoke design I had on my 1992 3.8.......
Hope you get sorted.
