My neighbor has a pair of these that are like new for sale. If anyone can use them, throw me an offer and I'll relay it. He just wants to get them to someone who will use them for a reasonable price. I'll ask him for a hard figure, but he didn't give me one yesterday when he showed them to me.
One thing to find out is if they are Bias-Ply or the Radial version. I can only speak of the radial version. The Radials are very nice good hooking tires on a well prepped track. The ones I got from Craig are great I love them. The only thing I would do different is go bigger : ) If you see the videos from Steve S. from Cedar Falls those are M/T E.T. Street radials 275/60 15R at Rock Falls they would NOT hook at all.
It would be a really tight fit in a Chevelle wheel well and would most likely require trimming or rolling the lip significantly. Then I would need to find 10" wheels with the perfect offset...
