I doubt it. the final drive ratio for 4EATs is 4.44 I believe while the 5MTs are 3.9 and theres just not enough demand to produce aftermarket diffs for us autos. You'll just have to give in to the dark side and do a 4EAT/MT swap

hahahah what a bummer, i have already gone 2 the "dark side" tho it was just a former thought i had been wondering about wen i had my auto
so dose this mean the only alternative is 2 use an auto WRX rear diff assembly and LSD 2 b able 2 use an LSD on the car at all?

soooo id have 2 get a rear diff from a 1989-94 turbo legacy or it wont fit at all? im confused....
on a differnt note i found out the out back has a rear LSD and its NA 4eat would an 05 or 06 outback nonturbo rear diff fit ? or is it only aplicable 2 the NA legacy and not the 2.5i imprezza

it all depends on the gear ratio, find out what your final drive ratio is in the rear end, and get one that is the same, otherwise bad things WILL happen
