There's nothing wrong with wheel spacers as long as they're properly designed for the specific car they're being used on. That means, they MUST be hub centric. That means, the hole in the center of the spacer must be the exact same I.D. as the Pantera's hub/register. This ensures the spacer is perfectly centered on the axle and that the impact forces of bumps and potholes are taken by the hub and axle, not the lug bolts. A proper spacer also needs to have a hub for the wheel to then register on. This is the way Porsche has been doing it for years. In fact, Porsche used 2" spacers on the rear of their early wide bodied 911's. I'd call the company you mentioned in your posting and tell them you want a set of fully hub centric spacers for a DeTomaso Pantera. I'm sure they can have a set made for you.
