My vote is that they are both ERA.
ERA GT40 typical rear and front wheel well opening and shape. A very correct car!

Cobra: top of doors where it meets the body flat joint and tunnel supports are too close together. 15" steering wheel and the rear view mirror does not have the fingers where wraps top and bottom of the glass.
