car-part.com shows your best bet might be Al's Auto Parts over in Trevose, about 60 miles awayI've got one, but it has bad bearings, which my guess is why you are looking for a new one yourself
You best bet might be to look for a 6spd trans. The Vibe, Matrix and Celica all share the same oneThe Vibe/Matrix are the only cars I have ever came across that the weak link is the manual trans and that the auto is more reliable then the manual Good luck
