Not many responses here or on the PY board. So just to be safe, I'll swap wheels/tires with my GTO, which has 225 70 14 redlines mounted on original HURST wheels. An advantage of doing this is that I'll get to see if I like redlines with the car, which is alpine blue/white top. It will also be cool to see what HURST wheels look like on my Firebird. I saw a Verdoro Green 68 coupe with these wheels sell at Mecum a couple/few weeks ago, and it looked fantastic (sold at a strong $42,500 btw). Unfortunately, I still won't know for sure about any rubbing issues given that the offset of these particular HURST wheels might not be the same as the JCs.
