I have a set of the GP2 grips that (I believe) do not have a traditional cap that would work with some pogies.
Has anyone either find a compatible pogie model or figured out how to attach those "retainer" plugs to these grips?
I have not purchased a set of pogies but would like to keep these grips, and as I understand the outer edge of the pogies has to be supported to the handlebar otherwise they sag.

Any ideas?

Here is the link to the grips I have:
