For almost thirty years I've owned a complete but non-running '67 GTO convertible that restoration will start on this winter (finally!). The only piece missing from the car is the tonneau cover, and I'm really hoping some of you can help me with information about this option and its configuration. The snaps are all there, on the dash and inside tops of the doors and on the pinch-well moulding, but the big question is the support brace. The sockets for it are there, one on each side on the B pillar, but I've no idea how it is constructed (what is it made of, does it fold... once, twice in the center?). The GTO Restoration Guide by Paul Zazarine mentions only that the tonneau was "an extremely rare option... on the 1964 through 1967... and was dealer installed," so no real help there. But from this, I'm believing it came on the car when sold new, and this fits with the rest of the car because it's nearly fully optioned. Way, way back then somebody wanted a 'Cadillac GTO' (ha) and went nuts on the option list. Thanks for listening and I'm sure hoping to get some replies in the Forum. If you should have any literature, photos, etc. on the tonneau, my email is [email protected].
