If i take the fiberglass frame of a Lincoln Town Cars cloth top off will there just be regular car underneath?

No, removing the fiberglass frame of a Lincoln Town Car's cloth top will not reveal a "regular" car underneath. The fiberglass top is an integral part of the car's structure, and its removal would expose the car's metal body and interior components. You wouldn't have a complete, drivable car left; it would be significantly incomplete and require extensive repair or modification to be functional again. The frame supports the roofline and contributes to the car's overall structural integrity.
