Patriot, does your Gun have factory steel butt plate and factory LOP?
I'll take a picture of the buttplate. I know nothing about these guns. Mine was my grandpa's. It's a 1963 model, so I'm not sure if they're a direct swap or not.
I'll take a measurement from the trigger to the butt so you can see what LOP is.
PM me with your cell number so I can text you pics later.
