Thank you to anyone that could help me on this. I have a 71 ranchero. It's been modified to be more of a street rod. The door sticker was removed when it was repainted. So here's what I found in the glove box. I believe I have many of the codes figured out, BUT..? The codes on the plate go as follows...typed out if my pic doesn't upload. 1A47H167418 P 72 66B ZR 09M 6 / W R I know how the vin works 1971, Atlanta, 500 Body, 351c 2V, Unit production # P- Medium Green Metallic Paint ??? (would make sense, some new paint is flaking) 72-Destination San Jose 2nd line 66B- Ranchero 500 ZR- Trim Medium Green Cloth and Vinyl 09M-????? 6- ??Rear Axle Ratio (maybe) W- C4 Transmission R- ??Rear Axle Ratio (maybe) If anyone has any insight I would appreciate it!
