Door codes for axle
Yep, I did a search and couldn't come up with what I need...
I am looking for a chart that works in the 73-79 truck years.
The Chiltons is too vague.
I would like to know a truck's factory equipped rear 9 inch axle ratio just by looking at the door code. For example, what is an 11J? There is no J in the Chilton book, nor is there a corresponding year with my '78 pickup, only much earlier years (like '65 to '70)

On occasion the printed codes can be shifted one way or another due to a bad alignment. A three digit code would indicate a 4WD model. Is this truck a 4x?
Somebody who frequents this site has a factory manual for the exact decode. Can't recall who... have seen it used before. If the numbers you show are correct, it is a factory non-LS unit. The only real way to know for sure what you have ratio-wise is to count wheel vs. driveline rotations, since people can always swap out gears.
