God bless America 
.....looks like I have the right outer pinion bearing for the 32 spline pinions. Thanks Locked79 for confirming.
Either one of the bearing part numbers shown in the pic will work. Both have identical part numbers. Shown is the issue that I was having....the usual 30306 pinion bearing designed for 27 or 29 spline pinions stands no chance of slipping over a massive 32 spliner.
I quick check with the dial calipers shows that either part number will fit just fine both inside dia and outside dia. for the 32 spline pinion.
These bearings are used on the newer 9.5" rear diffs I believe(here in the USA).
The 90366-33006 is direct from Toyota and it was back ordered and took 1 week to get to me. The one on the right is from JustDifferentials.com and took the usual 4 days to get to me. It's stamped the same exact part number and the sealed wrapper appears to be genuine Toyota.

The 90366-33006 race went in just fine into the 1993 TLC.
The 373 gears from Marks 4WD - Engine conversion, transmission conversion, low range gears, rock crawling gears and portal axles are yellow paint tested a pinion shim of .0495".
Drive is very shallow.

Coast looks shallow
pinion tooth confirms it's shallow.....comet tail deep in the root means shallow.

Little bit of old bump. Anyone used Terrain Tamer ring and pinion? They seem to list a 3.73 front and rear for the 80 series. One of my 4.11’s is going out (lots of metal) so want to look into upgrading at the same time.
