Hey fellas, resurrecting an old thread here.
Through a very lucky set of circumstances, I stumbled on an '85 442 in the wrecking yard here. Naturally, I first determined that it was indeed the 8.5" 10 bolt, and mostly confirmed that it had the 3:73 gears (about 80% sure). I checked the RPO code on the underside of the trunklid, and it did NOT have the G80 (posi) option. Seeing that it's definitely stronger and better geared than my 2:56's, I snapped it up today anyways.
Now that it's out and safely at home soon to go in, I tried researching the axle code stamped on the front of the passenger side tube. Unfortunately, nothing I've found on any of the common sites corresponds to what my stamping actually is.
Can anyone definitively decode and identify what my axel code is?
In case it's not clear in the photo, it reads:
8TF G 007
Thanks in advance for any help anyone can provide on this.
