Northstar, 4L60 combo

[Pete Datcuk]

  I am quite certain that the Northstar has a bolt pattern all it own.  I
know for a fact that it is different that the standard FWD pattern.  There
are four bolts across the top of the bellhousing, and two more at the very
bottom, unlike any engine/trans combo that I have seen.
  I am in the middle of a swap for my Fiero, and have the engine and the
4L80E Caddy trans.  I also have the stock FWD 5sp trans for the Fiero.  I
will double check this weekend.
