92 Loyale. Swapped to d/r five speed from pushbutton five speed. What are my swap in rear differential options?

if yours is not turbo you have a 3.9.

the existing driveshaft and diff will work

to use an lsd you will have to swap the 3.9 ring gear to the lsd carrier

 

you will need the e-10 socket for the axle studs

Great. What is an LSD carrier and where do I get it?

Good information here:

What car does the original LSD come from?

It was optional on the '88 to '90 GL turbos; it was standard on the RXs; in both cases it was a 3.700 which needs to be converted to 3.900. Check with qman or Dr. RX for that if you find one.
