I had them on my 94 plus 8 and they worked well so I kept them think they would fit my 2012 plus 4 but they don’t. The 94 windscreen frame has a square section and the mounting brackets fit easily, the 2012 frame is contoured with recessed screws so the two are incompatible.

I’d assume the actual screens and brackets would be usable but new mounting blocks would be needed.

I’ll dig them out and take a pic if that’s going to help but I’ve quite a busy few days ahead so it may be Sunday or Monday before I get the chance.

2012 Plus 4 in Sport Green. Much comfier than the Plus 8!
