Gene Evans sells regular 99 wheels that they are calling special edition wheels but i believe they are just 99's. They arent polished like the real 35th anniversary wheels.
$90 a piece.
I almost bought those wheels, but I wanted a 9" width, so when the 03 Cobras became available I bought them. But theres a 94/95 Red GT that has them that I see every once in a while and they look fantastic IMHO. I dont know why, but I love those rims in the SN95s. If you can find them cheaper Id go for it.
That car in the link makes me cry because I had an identical '99 GT with those rims and two tone leather and a drove it through my friends truck - that car is no more - Im a ****in idiot.
