First off, your VIN is a scramble of numbers and letters in the incorrect order! Your 1968-1980 VIN should read:
First character - Car line
Second character - Price line
Third & fourth characters - Body style
Fifth character - Engine Displacement
Sixth character - Model Year
Seventh character - Build Plant
eighth-thirteenth characters - Sequential Build Number (100001 - up)
Example - DP23H76100036
What car are you trying to decipher the VIN on. Please go and recheck your numbers. That does not correlate to a 1965-earlier VIN sequence, either. A 1965 and earlier look like this:
Example - 425224900
First two characters are make and model. Depending on the years 1962 - 1965, the first character could be a number OR a letter. My example shows a Coronet six-cylinder as the first, and Coronet as the second character. The 5 is 1965. The 2 is Hamtramck, MI. The rest is the sequential number.
First character - Car line
Second character - Model
Third character - Model Year
Fourth Character - Build Plant
Fifth - Eleventh characters - Sequential Build Number
So, in 1965, your D8 would be a Polara V8 Taxi. Is that what you have?
I'll clue you in on something - MOST of those "VIN decoding web sites" SUCK and are terribly inaccurate. MOST...
