Not sure about other frames, but on this 62 C20 the frame is boxed in. Inside the frame there is internal bracing around the stock box holes. The hole I circled landed directly on the internal bracing. You can't see it that well but it is there. I wish I could say I had an easy way around this, but I didn't. I essentially stuck the cutting torch in the hole and blindly cut and melted the brace inside the frame.
