S10s don't come in 6 lug, they're 5x4 3/4 only. Also, the newer Colorado is out, too. While they are 6 lug, the bolt circle is smaller, roughly 5" (actually metric) instead of 5 1/2".
You might be able to find spacers/adapters through American Racing or Cragar. They will move the wheel out at least 1".
