Anyway, that's the problem, and I have the harness set installed! It seems that my harness matches a '78-'79 Ford truck. The key on the harness is smaller than the factory buckle. Is this smaller size a standard and if so, what dates--oh, please? How can I track this and where can I pick up a set of lap belts/buckles ?
