Rear axle questions

[Dirtball@domain.elided (Paul Brakefield)]

Hope some of you guys are still out there who can answer my questions ASAP.

I just removed my rear diff cover to change the dope.  Two tags were still
on the outside of the cover.  One says "use only limited slip diff lube (or
something to that effect)" and the other has a 43-1 and 3.31 stamped on it.
I know what the limited slip diff lube tag means, and I assume the 3.31 is
the ratio.  What does the 43-1 mean?

Second question.  I know I have either a Power-loc or a Crap... er, I mean
Trac-loc.  When you look at the carrier there are the two spider gears with
what looks like two smaller spider gears between them.  Please tell me that
I'm looking at a Power-loc.  Seems I remember reading that that was one way
to tell.

I need to know quick!!
