I have in a 355 diff out of a 67 BB, date coded in 1966. This appears to never have been touched, still had the Hyatt bearings in it. The odd thing is the carrier (housing) is the later type used in the 69-79 run,it has the thick cast shims and is the wider version. I think I may have had a similar 66 or 67 like this a few years ago, but usually they have the narrower housing and thin 080-090 shims.
Any reason for this? I thought it might be a '76 housing but it's not. The internals are all 60's version. Along with the bearings, the posi is the first design used from 65-68. It has the HD yokes and1310 yoke.
