Got some Mercury TII questions...

What's the correct height on the adapter/spacer between lower unit and leg ??
The reason for this question are me getting a little confused

I got 2 or 3 3-3/4" adapters/spacers ( some with a guide tube for shift LU )
and one 3" adapter/spacer....( some came with the engine, some I found....Ebay )

second Q
What's the shaft length on the the different SSM models ( TII, TIIx, STD inline ++ ), so I can properly identify my SSM.

In the end this will give me the correct length for the shaft extension I need ..
