Try to find a GTB Liberty or a STI 4.44 box (same) even though they are a 4 bolt they fit straight in & are a fair bit stronger, usually get one with a diff for around the 2g mark & the RA ones are a pain in the arse, especially living in the country,.
My ex blew 3rd without even trying in my old MY00 & I ended up driving it about 30k's & it did no further harm but I was lucky, I replaced it with a 98 4 bolt without any probs.
