MAKG, I have already posted what I call, an "updated" thread (with pics) of AllanD's field disassembly.

Well, I can show how to know if a part needs replaced or not, and that in itself is a gray area cause a part that I may say is bad is something another may say is still useable.
Case in point...I have a 2nd gear that the cast syncro ring has broken off of, and as the trans spun, it rewelded itself out of sync. This is not something one would see unless they paid attention as the trans was disassembled.
So I will be sure I include pics of bad parts, and explain why I would not re-use them. Some will be obvious, and some will not, though I will point out WHY I am tossing them out as "bad parts".
