again.... the best advice that you received. was given by Dean of DGR. a very noted M1 Garand smith............paraphrasing Dean,....... to replace parts to return your rifle to a correct status is your choice. But if you do replace the bolt with another. it MUST be checked to see if it head space's correctly on the barrel....... regardless if it is the correct revision number or color........... it Must headspace as good before you can leave it in the rifle..........If it was mine... I'd have it headspace checked before I bought the replacement bolt...............
be safe, enjoy life, journey well
