Paging Jeff Lange... Paging Jeff Lange...
(you guys probably don't know of him, so it's kind of wasted...)
Anyway, I sent a message to Jeff... the guy is a human Supra encyclopedia (and other cars as well) it's creepy. I once heard that he actually was the brains behind the Supra altogether and he directed the design and built of the MKIII from the womb!
No, really, the guy knows way too much about these cars and works for a Toyota dealership in Canada (so he can look up what Toyota's internal publications called it... if they even did call it anything different).
JDM style blinkers? The JDM blinkers for the MKIII were amber.... unless this was a special change for half a year. The only signals with clear in them that came from the factory, AFAIK, were for the European markets and only half was clear (they look really cool, too).
I hope Jeff emails back soon, I really wat to know what the deal is now too. So, Green, where did you come across a 92.5 (or whatever) anyway? It's an almost unheard of topic.
