I replaced the carpet this weekend and was disappointed when I didn't find the build sheet under the seat springs. However, when I pulled the carpet out, the build sheet was under the carpet on the passenger floorboard. Is there a decoder for the build sheets anywhere? Some of it makes sense, but parts are a mystery to me. The biggest question is that the build sheet has an "R" under the Camper Special Package. There was one Camper Special logo on one front fender, but I wasn't sure that the fender was original.

So, I have 2 questions: 1-What options made the truck a Camper Special? Does the "R" mean something more than just denoting this is a Camper Special?
2-The rear axle code is D221R. Anyone able to translate that into English?

Truck is a 79 F250, 2WD, Reg Cab, Ranger XLT, 460 Auto, Factory A/C

 

May not always be a sure sign, but does it have the dual batteries? How about some pics and your VIN off the door. Might be able to glean more info from that.
Numberdummy is the man when it comes to decoding the VIN.....

 

It doesn't have the dual batteries.

Let's try this one.


Any better?

 

VIN F25JREC7541
F25 - F250 2WD
J - V8 460-4v
R - San Jose CA Plant
EC7 - 1979
EC7541 - Sequential Serial # per plant

DSO 72 - San Jose CA



My build sheet also shows the letter R under the Camper Special Package. I don't really think it denotes anything other than it was specified. Also, on the axle code, my sheet also shows four digits but those are internal Ford use build codes that don't necessarily correspond to anything we'd be able to decode. The actual code is C7X. I looked up axle code C7X and found this thread: https://www.ford-trucks.com/forums/1...-code-c7x.html



This page from the brochure shows the Camper Special specifications.

I'm a little late to the game here, but is that a thing? Finding your build sheet under the seat springs? Tell me more.

 

Thanks ND and RogueRiver, that info is helpful.
