What's a fair price?

[Racie]

I've been searching trying to find a set of American Racing Torq Thrust II's with the gray centers 20x10 and 18x8's. Problem is there seem to be none forsale and I can't find a list price of them new. I'm about to start new mods on my 68' with tubbs and billet wheels. One of the supervisors that works for me wants my old Torq thrust but I want to give him a fair deal but not rape myself either. They are spotless no blemishes or scars and have the new knockoffs on them also. Rubber is about 70%. Anyone sold or bought a set lately?
