Actually the first year for in HOUSE (GM)Napco conversions was 1957
Before that they were done by outside vendors. The way to tell is the rivets on the tranfercase crossmember,when done outside the factory they had bolts, the conversion was originally sold so that it could be taken off and installed on another truck and the original truck restored to pre-napco condition.
Here is a pic of a 57 Napco I use to own
