I doubt it.
Since I doubt anybody can mind-meld the present exact size & shape of YOUR A-5's cut off buttstock, it's up to you.
What I do is set the bare wood butt (less pad) down on a 3"x5" index card & trace around the butt's outline with a pencil.
I'd label it "A-5" inside the outline & cut the outline out of the rest of the index card with scissors, before I fold it up and place it in my wallet & go shopping (funshops, funshows, gunsmiths, whatever).
At least you should be able to use the pattern you made to obtain something close to what you want.
