Thanks, Mayf.
I would definitely prefer 2.88s, but haven't found any readily
available. Also, I am a bit concerned about installing a used gear set.
Although it would likely be fine, I wouldn't want to find myself needing
to do another swap if it didn't turn out well.

Shaun, going to 3.07 will only reduce you rpm by just a shade over 9%.
So If you have been cruising along the interstate at 2700 rpm then you
might expect a drop down to around 2450 rpm. You will get a better
answer than wha I am about to give you but the bottom line is is that
the LSD has a different bolt shank diameter than used on the 2.88 gear
set. I am curious as to why you do not consider the 2.88 used. Our cars
are lightly loaded so there is no real stress on them and so wear, if
maintained should be very little. Heck, try a used set then if you do
not like them, go to the 3.07 ratio.
