Roof Rack for my 66

Has anyone used any "universal" roof rack on your car? I have a 66 4 door sedan that I take on road trips and camping. I might end up carrying boxes up there at some point but I'm mostly interested in being able to mount a single large solar panel.

I'm not interested in anything that requires holes to be cut but all the clip style ones I've seen look likely wouldn't get along well with the gutters over the doors.
