I’m wanting to remove the old butt pad and add an out of the box fit recoil pad. Any recommendations on brand / model. I looked at a few sites but didn’t see anything for the pre 64s (if that even matters)
You are not going to find a "pre fit" for a pre 64. Do like handwerk said. However, is your rifle original? Original "butt pad"? I'd not mess with an original, if it's in good condition. If it is pre '59, it's going to likely have a widows peak inletted for the steel butt plate. The stock will not look right with this inletting and a recoil pad slapped on top of it. There is also a slight curvature, so to do it right the stock needs to be cut straight. This drastically reduces the value of the stock. If it is not original, no big deal. If it is, look for a "shooter" stock for your rifle..
