I have viewed the Tech Page located at: https://www.stovebolt.com/techtips/identification/Series/#fifty
for information on the VIN Plate of a truck I put a deposit on. It was helpful to help me decipher the VIN. However, there are 3 additional codes on the this plate that I was hoping one of you could educate me on. If I knew what these codes were, then I could search for "Option Codes" "Paint Codes" or "Engine Codes" etc., but I have no idea what I am looking at. Just typing the codes into the search here didn't yield any results and I got nothing when I tried websearch as well.
I attached a photo with the codes to this post. But in case you can't see it, "MTC" is stamped in the upper right corner of the plate and "C51" and "232" is stamped right above the VIN number.
Any help would be greatly appreciated!
