I recently tried a pair of flexi blades that accept a pin fitment. Unfortunately, the plastic blade body is thicker than its metal equivalent so while the pin does fit, it is no longer centralised and therefore does not lock onto the spring retainer. It's only a matter of a few mm and I guess if one was handy with a dremel then you could modify the pin but that then again, I don't have a dremel anyway.
Has anyone tried MK1 MX5 arms or come up with a solution?
