That's a bold move completely breaking down the tranny.... And no pictures to back you up. I broke mine down for cleaning and inspection on more of a component basis.
Search my posts. There may be some useful pics and info.
The Fiat shop manual omit the fourth gear syncro spring in their drawings.
I, also, have been using Redline MT90 with good results.
Very satisfying to rebuild your own 5 speed.

Thanks for the kind words and help. I have been pouring over the search function in this list and google as well. I found the cross section diagram to be helpful. With a little study you can see where spacers go and what thickness they are. As well as the orientation of bearings and such.

It will not tell you which way to put in spring washers but then again knowing that it is a spring washer will tell us we need to find out. I have been deducing how things go in by the wear marks on them too.


Here is a good scan of the cross section diagram from my service manual.
