901 gear box pix please

[TRE Cup]

hi guys- we have a client in spain, and besides the language barrier, we also have the mechanical understanding barrier. So.... to make things real easy, i need to send him pix of the output flanges installed on the trans. Both the nadella style, early lobro (68 ) and later lobro. Can anyone help?
Thanks!

Here is the Lobro flange for the early (non-simplified) differential.
Note the lack of teat on the stretch bolt and the plug with
O-ring seal as the earlier Nadella has.

In ’68, the “simplified differential” did away with the plug and
the bolt had a locating teat. This was a disaster for ’68-’71
because the teat would wear off and the spider gear shaft
would move out and destroy the transmission.
