The plastic capping that runs around the front, center and rear glass of the factory t-tops on my 84 Z28 are splitting. None of the weatherstripping kits I have seen include this part. I don't know the correct name for it but it looks like a u-profile black plastic capping that pushes onto the edge of the glass on three sides, while the fourth (outer) side is where the drip rail seal goes. There is a thumbnail around that shows all the t-top seals. I have copied this and hopefully this has attached itself (I have never tried this before). If so, it is arrowed by the number 1 arrow. If attaching the thumbnail failed, I hope the description made sense. Does anyone know what this part is called and where I can buy it?
