I am intrigued with the thought of manual windows for the rear of a coupe. Think you could pull enough stuff out to transplant it into a coupe with power windows? What about visors? What color interior? Outside mirrors? Door panels? Windshield? The weatherstrips in the door frames that go over the windows are worth pulling if they are good.

You may be able to unlock the trunk with a Mityvac, in theory, never tried it.
