And mine isn’t in a 1968 SWB, but rather one of the earliest 1969 LWB cars.
But a late July 1968 build. And Nürburgring gears picked to race at ... Nurburgring!

A few pictures of my 906 R/P. It seems the castle nut arrangement is a carry over from 356 design?
Great 906 parts Brad!
Claudius, the simplified diff has nothing to do with the ring and pinion, they did not change. The difference is in the guts of the diff itself where the spider gears are and how they are supported. The simplified diff has bolts that secure the output flanges into the diff. There are tits on the end that can wear and break off; when they do the damage is catastrophic.
Good information in this thread and links from it:

I got it. I thought it is a different shape of the bevel-ring gear, but they are the same in both simplified and normal.
