Vintage rooftop cargo-box, I picked it up a few years ago, but I've never used it.
I have all the mounting hardware saved in a bag. These boxes are vintage, made by Thule for distribution at Sears stores. I have the key, bought using the Thule key code # that's on the lock cylinders.
Cash only. Pickup at my house.
