Ebay is an awesome source. I think "BonesIndustries" or something like that carries alot, havent bought from them though, so I dont know how their service is, but I do know they carry alot of wheel / wheel and tire packages for our trucks.
You really do like the looks of those wheels on Jimmy's Ty, huh? I can't blame you....I like the look too and would sell you that set but I am acquiring another Sy real soon and have plans of putting them on it. Try the Camaro SS forum "for sale" section in addition to ebay IF you want a SLP set. Those guys are a bit more honest in their description. Their are some aftermarket companies that have copied the design for cheaper $$$.
These are just replicas, but with a little job from my painter, I think they would be perty'!
I want grand sports too, do they fit good in the back, they sure are big.
a few months ago there was an awesome deal on some mint grand sports on here, if I had realized how good of a deal at the time I would have bought them.
