Build Sheet codes

thanks for the reply Terry.....I don't think there is. I don't see anything on my buildsheet....once I get her back from the shop, I guess I'll just have to do a burnout :)
I checked the 8x11 Fremont sheet from my '72 442 and didn't see an obvious reference in the code boxes. Do you have the options listed below the boxes on the sheet? You would see a G80 if it's a posi (they're listed alphabetically).
Hello SX owners...a newbie here. Just purchased and transported a Freemont built '70 SX L33 back from Flint Mi. to the state where she was built. I have a question....can you tell from a code on the build sheet if the car came with a posi rearend?

I promise pics in the near future!
