Long story short, I have an SPS-T 20 guage that I love.  I have a youth stock I would like to install but it has no butt plate and is hollow.  My gunsmith had no interest in helping me out so I am looking for any help I can get.  Does anyone know where I could find someone to make a butt plate so I use this stock?  I would likely just add a limbsaver recoil pad overtop of it and it was suggested I fill the stock with spray foam?
Any suggestions, help, or contacts would be greatly appreciated.  Thank you, Ron
