Before starting , pull the stock off and check the front of the reciever. Some had pieces of the reciever cut off below the wood line. Also see if the welds are small tack welds or are long heavy ones. Big welds could weaken the reciever metal. Finally , check for the reciever being drilled for a cross pin or blind hole pin through the chamber to either block it or hold the rod inside in place. No use spending money if it's non-restorable.
