I have a Surrey top in great shape. It is a dark gray color, and I believe it is the OEM original surrey top. It snaps over the horizontal bars to the adjacent/above to the driver and passenger doors and requires the header bar above the windshield (which I am not offering for sale here).
Like I said, it is in great shape with no rips, tears, stains or odors.
Asking $350, plus shipping.
