I recently acquired a nice Savage 99 (box magazine model) in .308. It has a tang safety issue. The safety is off & does not want to go on. When I removed the stock, the safety slide was loosely attached to the safety button by a "glob" of soft solder. I am not sure if the safety slide has been spoiled and this solder job is a patch job fix from the past. I cannot seem to find a good description, view or video of how the button and the slide are supposed to connect to each other in the frame slot. Any help would be appreciated.
