I'd like to have concise reliable info in 1 place. Is this the best source?

YES.
It is the best source for transmission technical data..

Make sure you get the right one. That one is for the 6 bolt pan version.

I counted 6 bolts on the 85SD pan. I'll probably order it unless I find it hosted somewhere. I found the manuals for my other vehicles after buying the manuals. Not a huge amount of money & probably better to respect copy right laws.
