Fender tag codes

The "fill in the blank" online decoders are crap, in my opinion.
Based on the combination of the codes you have a 1968 base model Dart 2 door Sedan
I figured out the year by the paint and the interior codes as the model year in not on the fender tag then.

Read from the bottom up:
LL21 - Base Model Dart 2 Door Sedan
21 - 225 1BBL 6 CYL 145hp
5 - Torqueflite Automatic Transmission
13 - 7.00 x 13 White Wall Tires
909 - SPD Sept, 9th. 1967
A10505 - Shipping Order Number
A1 - 3.23 Axle Ratio
Trim L4X - Vinyl Bench Seat/Black, Black Rubber Floor Covering
PNT MM1 - Bronze Met. Paint
UB - Upper Door Paint, Black
W6 - Canadian Order
