I had that problem with mine. You'll need the window seal for the flipper glass and an additional piece that looks like a rain gutter. It fits across the top of the glass and diverts water to the sides. If you're having problems with the dome light staying on and gate appears across the speedometer then you'll also need a gate switch because of water damage. There's also the possibility that the center brake light gasket is bad but that's not likely to be the case.
