But will this tell me if the axle and/or gearing I've got (8 1/4" w/ SG 3.55) came from the factory?

END: End of codes.

Now, there's no axle-related code here. No D56 for 3.55 ratio, no D82 for 8¼" rear axle, no D91 for Sure-Grip. This leads me to believe the car left the factory with the standard 7¼" open 2.76 rear axle. I could be wrong on this; the build sheet would go into some detail on the matter.

That Y39 "Ordered vehicle" code usually just means the vehicle was ordered by the initial buyer, rather than just being purchased off a dealer's lot having been made on spec by Chrysler.

Dan, you never cease to amaze me with the Mopar knowledge you've acquired over the years. If I'm ever up your direction, I'll have to stop by and treat you to a bottle of quality beer (ever heard of Arrogant Bastard?).

Yeah, people call me that from time to time.

...Oh, it's a beer? Never mind.

Aye, and a VERY good one. My favorite. I even had a vinyl decal custom cut of the gargoyle on the bottle to put on the Duster when it's all fixed up nice

Looking at the info you posted Dan, and I saw you mentioned Space Duster when referring to the fold down rear seat. Was that an uncommon option or part of an option package of some sort?

I wish I could get my hands on the build sheet for it, but the PO replaced the (completely shot) front bench with a bench out of a later model Dart.

Have you checked under the rear seat or inside the rear seat back ???

Not yet. I've still got a few nitnoid things to finish up before I start to tackle the interior.
