Don't know about the newer type, but last year I asked the same question about the stalks on the eighties +8. No real answer so took chance and gently Bent them...,worked ok. Please don't send me the bill if it goes wrong... Check first.
The 1980s car stalks were thin metal tubes covered in plastic and had to be bent to get them to fit. It's one of those jobs that you have to do firmly but gently, and in one go. I think they come from something like a Triumph Dolomite originally
I have no idea about the later switches, but it wouldn't surprise me if they were similar.
