The inner door sill plate is the black piece of metal that fits on the inside of the door opening at the bottom. It holds down the door gasket as well as the vinyl piece or carpet piece and is held down with some screws. We also sell the screws, see listing or call.
We now use these sill plates on the 74.5-78 coupes because the plates for those models have gone obsolete and no one is making them anymore. Other than redrilling the holes in the body, they will fit fine. For the 2+2 models we also use these plates although to get full length coverage like the original, you need to use 1 and a half of these plates and they do require some special trimming to fit properly. Otherwise, partial coverage works ok and is easier to install. These units are the same length as the silver outer door sill plate.
These units don't weigh as much as we have them listed for but we have to list them this way to get a closer to accurate shipping price. If you order 2 to 10 of them, the shipping will still be about the same price as when you order 1 unit. These pieces fit either side of your z. These units also require special packaging to prevent damage in shipping which does cost a little bit extra and is figured into the shipping rate.
If we happen to be out of stock please allow an extra week for delivery.
