Meet my new Model 27-2 3.5" .357 Magnum revolver.

I'm planning on getting some ivory stocks for it, those are gonna be easy to find. But I'm having trouble finding one thing that I've been looking for.
A grip adapter like one of these:

I can find Tyler-T adapters, Pachmayr adapters, and a couple custom ones, but they all extend down the length of the grip vs just at gap between the guard and grip and attach too low to cut off (and in the case of the tyler it's too thin). Any ideas on where to find one like these?
Yes, I do plan on pulling a Patton with my 27 haha.
