its just an r160 diff

so you can make anything fit of that size, L series, wrx, rs, all the usual suspects

you can either pul the rear cover off the diff and count the number of teeth 37=3.7 and 39=3.9

or you can jack the back of the car off the ground and put a mark on the wheel and the tailshaft
then you just count the number of turns it takes the tailshaft to spin the wheels once

eg 3.7 turns of the tailshaft to make the wheels turn once = 3.7:1 ratio

or you can just replace the diff centre with a LSD one

You forgot to add that later model R160's (95 onwards or something) don't have stub shafts on the diff, they have the stub on the driveshafts joint. I think the joints are different too so it would require some driveshaft modification (chop and weld I assume) to fit on of these diffs in a narrower track EA81 car.

ta think i'l pull the back of the diff of and count it this weekend. would change the diff centre aswell but things are a bit tight with the cash flow at the moment

A CLSD from an 85-89 Subaru RX should bolt right in. (not sure on the exact years the RX came out but someone will correct me.)
