I have 3 holes I need to fill and Numrich did not seem to have the anwers for me in their hard to read schematic. thanks for any help. Serial # dates it at 1968
Right Side - hole just above the loading gate

Left Side - hole where it looks like a saddle ring might go

Left Side - towards front in middle of pic - looks like a pin may be in there but still leaves a hole.
