4 to 3 spoke steering wheel swap

[8690q]

The steering wheel on my cabriolet is falling to bits and I fancied treating it to a new one.

I had a 3 spoke that I liked in my old 80 but they seem to be getting rarer and more expensive.

I like the b5 steering wheels but only as they are a good bit cheaper. I'm sure I've saw them fitted to b4 cars.

Just wondering if anyone has experience of fitting a later steering wheel to an earlier car or am I better saving my pennies for the right wheel ?
