Warning: there is a chance that the folding panel has TWO latches spaced about 2 feet apart. This was apparently a random variation on the production line... we have observed examples of 67, 68 and 69 fastbacks with two latches — there doesn't seem to be any pattern or logic to it. The crazy thing is that the sheet metal inside the opening has to be different to use the one latch versus two latches. It also changes the location of the trunk lamp when the lighting package is fitted.
So, anyway, if you can't locate a center latch, try looking for one on each side. I will try to find a photo showing the locations. My fastback has one latch, as shown above.
