I ran into this too. Don prefers you call him and discuss what you want. Great guy to deal with and does great work. If you do go with Don make sure and have him provide the butt plate too. He'll also install a trigger guard if you want but he doesn't do bedding the last time I got one of his stocks.
I have a stock maker that I’m sure can make you exactly what you need! He is busy and may take some time but he does excellent work! 304-266-0081 is my cell if you are interested
