W460 Year 82. Which steering wheel was original’?

I have built such a thick steering wheel. Which is probably at home in the w123. (4 spokes) Now I know, but there was original such a steering wheel with a thin Holm(2 spokes). and in the middle then a Mercedes or Puchplakette. Now I wonder, there were original 2 steering wheels in the year 82. Or was there only that with the thin Holms. Then, yes then, I would like to disarm on the old variant. And is it easy to exchange? Thank you for help.
