Top Mount Covers

[KitsonRis]

Looking at getting these to stop the crud getting into my nice shiney PMS top mounts. Asked the seller, who makes them, if they will fit but he is not sure. Anyone know if they will, or know of any top mount cover that will fit?

Could some machined? How do they fix on?

I think the ones in the link push on to the rubber bits, but there isn't anything to push over with the solid top mounts

A thread to screw onto?
