Howdy Corolla enthusiasts. I'm in need of a new diff for my KE70, i've heard the T series diffs are the way to go. I am planning on putting a 4AGZE in it and was wondering if that is still the case and if so where should I look. I've seen some people have luck finding T series diffs out of RA60 Celicas. There are a couple of unnames 3rd Gen Celicas in the yards around me. How would I know if they have a T series (sorry, I'm a bit of a newbie). Thanks in advance!
