I have a 1949 3100 truck. I was wondering, would the shock towers off a 1954 truck work. By that I mean would it be a bolt on swap? Are the holes already drilled in the 49' frame? I see some holes in the frame but not sure if they're the right ones. Don't want to cut them off if they want work. Some day someone might need a 54 frame. Thank for the input.
