Tried my best with the VIN provided. I have the book of codes if you have the complete VIN and identification plate.
W912 - LNT9000 Chassis Cab, Diesel, TandemV - 12.1L Detroit 8V92
E - Assembly Year C7515 - Assembly Sequence

W91 = LNT 900, diesel

2 = Detroit 6-71N OR Cummins NTC290 six cylinder diesels. (Where did you find an 8V92 under that engine code?) OP can confirm what it is.

V = Kentucky Truck Plant

EC7515 = 1979 numerical series, I can't determine the production month.

You should have a certification label with transmission and axle info etc.

Yes 6-71 Detroit 13 spd not sure why such low gears probably 4.88 or slower lol can start in 4th no problem. It has an aluminum tag on the door with just the VIN #. Will look again it might have a sticker on B pillar (door jam) below striker plate, I think it is either faded out or painted over.

1979 has the Warranty Plate (with all the codes stamped on it) and the Certification Label (VIN and misc jazz). 1980 only has the Certification Label.

It is located on the left door face below the latch, where the Warranty Plate was located 1963/79.
