Thought I’d add some trunk information.
The pinch seam luggage protectors came in either black or gray. I’ve seen both, but they seem to be predominately gray on 1968 Mustangs. As someone mentioned, they are held in place with yellowish glue. Some are notched and some are not.
The trunk lid springs either had an anti-rattle clip or the spiral rubber piece. I’ve never seen an original car without one or the other. I’ve also never seen a car with both. The anti-rattle clip is either painted red oxide or body color. The spiral rubber piece is sometimes painted body color (I know what you’re thinking, they must have gotten painted when cars were repainted. But I have an original paint San Jose convertible that has never had any paint-work done, and it has the spiral rubber piece painted). The spiral rubber piece (if original) has 3-stripes molded into the rubber.
Somewhere on the GT/CS website there is a long thread on trunk mats. I’ve seen the speckled type mat and a matted material type which looks similar to the speckled mat, but un-painted/speckled. I know there are cars with the plaid mats too, I just have never seen one. My HCS has a speckled mat.
The tabs that hold the wiring harness should have the rubber boots on them, as someone mentioned. And as someone mentioned, they are only for holding the wiring harness, not the cardboard protectors. The cardboard protectors are notched to go around them.
There are gray protectors that go on the rear quarter panel protector studs on the driver’s side only (I think). The spare tire protects the other side.
I have seen 3-styles of original jacks and 4-styles of jack handles. I think all variants were used, just depended on what the factory had at the time.
Some cars seem to have sound deadener on the gas tanks and some do not. All coupes have the sound deadener behind the back seat.
The best way to bend the trunk protectors is to lay them over something of approximately the right radius and spray them with water and let it dry. They will then be bent enough that they can be installed. I use a 500-lb WWII practice bomb and large rubber bands to hold the protectors in place while they are drying. You will almost always crease them if they are not prebent. They are only painted on one side and are stamped “FP” in the corners.
