This was the question I put out to my tech buddies: If I purchased a posi
spool could I just drop it into my 3.7 diff and away I go? Answers came back
about having to install shims for backlash and other things like the fact
that the offset on the spool varies and that some can modified with spacers.
As far as I can tell, it's not as easy as just dropping a posi spool into
your diff.
I had originally thought a 3.7 LSD would be great as I could get my
positraction without having to deal with high RPMS at freeway speed. Perhaps
a 3.9 LSD would be the way to go.

The diff and the ring and pinion are different parts. You can put a 3.90
ring and pinion onto a limited slip diff. I currently have one with 4.38
gears and am looking for a 4.11 instead. The 3.90s are readily available
used as are the 4.38's. If you want to find out what 4.38's are like on the
highway, just leave it in 4th gear (assuming you've got a 5 spd). The
overall ratio with 4.38's in 5th gear is 3.72 - almost exactly the same as a
stock 2000 in 4th.

Was there a 3.9 LSD? (1600 is 3.9) Would that be a good compromise?
