Whiteline told me they were thinking about doing a sway bar for the ae102/101 corolla back when I had one 3 years ago. I don't know if they ever actually went through with it. I sold my car & suddenly parts for the ae102 weren't as important to me anymore...
Whiteline do have a pretty good rep & are probably good people to talk to.
I expect you'll want to know about the 7A-GE in the next little while then?
