To digress just a bit ... and I don't have any Cobra tonneau cover experience just yet ( need the car to be finished first
) ... but I can pass on one interesting feature from the tonneau cover on my TR6. It has a strap attached near the zipper area, on passenger half of the cover, that hangs down near the hand brake. There is a post on the side of the transmission tunnel that the strap snaps onto (provided the post has not been removed of fallen off). This puts some tension on the cover to keep it from moving around quite so much.
The end result is that the passenger side cover does not flap around as much at freeway speed, but that's 60 to 65 mph in a TR ... which with skinny tires and wimpy brakes is fast enough ... but Cobra freeway cruising speeds would be somewhat higher ...
!
Not sure how well it would work in a Cobra, but it could make the passenger side cover flap less. The nice thing is, at lower speeds on a cold day with the passenger side tonneau cover on and the heater going, it does help to keep the chill off of the legs.
