For your example, "say a mid-model year change in a transmission part?" "Would a repair shop have any need to investigate the VIN in ordering parts for a 62-65 Mopar?"
Not in this case. The 62-65 transmission is identified by it's 10,000 day calendar number on the side rail. It identifies the transmission not the VIN.

Subject: 62-65 VIN
Hi - I understand that the VIN on newer cars with 17 digit VINs can be used to identify parts numbers, especially if there have been mid-model year part changes. My question is whether the sequence portion of the 62-65 Mopar VINs can be used for similar information, say a mid-model year change in a transmission part? Would a repair shop have any need to investigate the VIN in ordering parts for a 62-65 Mopar? Thanks
