Whew ! Just finished reading all this and would like to say I believe you and I..somewhere down the family tree, might possibly be related....lol. If I had the shop and $$$ I would resto mine a lot like you have done. Although my 64k 89' is clean..it is not perfect, and I would LOVE to make it so. Your thread has helped me realize more so, and understand, why myself, you, and all other Supra lovers out there are the way we are about our cars. Kudos to you for sharing your car with all of us and taking the time out of your schedule to do so.
On another note, I dunno if you are dead set on the Kinesis wheels or the HRE's or not, but I would like to suggest (if I may) a set of Konig Afterburner's..Black w/prizm lip. I selected this rim after I thought about your car color, trim molding pieces, and all the other shiny detailed items.. I believe these rims would complement your car the most. Here is a pic:
Anyway just wanted to suggest them...Keep up the awesome work !!
