Hi Guys, looking for a little information on 1969 Muncie transmission stamps. I’m in the market for an Original 1969 Muncie M22. It’s for a driver quality 1969 Camaro. I’m not concerned about month date codes. I would like at least a real 1969 M22 of quality for my car. So my question is this. Was it typical at times for 1969 Chevrolet Muncie‘s to not have an A,B or C stamp to designate an m20 m21 or m22? I’ve looked at several used ones available for sale. Some have the A B or C stamps, others don’t. The ones I’ve looked into were not over the counter replacements. They all have had Camaro Chevelle etc Vin number stamps and Build date stamps. Just missing the single letter transmission stamp. Any clarification would be helpful. Thanks Rob
