[Spits] 79 Differential in a GT6

[Todd Bermudez]

All,

I've sourced a '79 Spitfire diff for my GT6.  I have
not received it & probably won't for a several weeks. 
But it's cold & I'm in no rush at this point.

My question is the 79 a direct bolt in replacement for
a GT6 MK1?  Meaning are there 6 stud holes(on top) on
the later diffs or only 4.  If there are only 4, do I
need to use the back half of the GT6 punkin'?  Not
done this before so please be gentle :)

Cheers,
