I bought what was described as a rebuilt 1985, limited slip, 915 box sight unseen. Now that it has arrived in Thailand, I am not sure what I received

Stamped on the bottom of the box is:
915/6112 718 5747
What does this tell me?

Both flanges rotate in the same direction, so I am presuming a LSD - is this a valid assumption?

I do not see any sensor for the electric speedo and the only sensor is a switch on the nosecone. Is this a reverse switch?
Where does the speedo sensor go?

There is no lever arm on the clutch release shaft.
Does anyone have one, or what else can I use?
Machine work here is cheap, and I have bought the Aircooled.net hydraulic clutch kit only to find that it is LHD and will need a new MC bracket

What is so special about Swepco oil?
It is not available here and I was thinking of a synthetic gear oil

Thanks
