An Aluminum gutter. Two piece snap on type which you bend to the roof contour. Fasten the flat piece to the roof, and the the gutter piece will snap onto it. Will work on any car that has wood to nail into where they mount. One set does both sides. When bending, you must snap the two pieces together and bend as an assembly. Use wax paper between the two pieces when bending to make them come apart easier. These gutters are 45" long and are used for pickup trucks and coupes. U.S.A.
