TH350 and 3.23 or 2.73?

I have had it with the 3.73 on mild 350ci I cant cruise anymore so Im changing the posi and 3.73 to 98+ torsen and stock gears but cant decide on which gears,will a 98+ limit slip will fit my '92 Z28? Mine has posi but it was acting up lately and I read somewhere I can swap to torsen from factory 4th gen

i ran 3.42s on mine with a th350 for a while and they were quite tolerable
for highway use,but 3.23 would be a good choice for non-OD tranny use.
The torsen carrier i bought to use in my original axle had 3.42 gears.
