One important note on the plastic trim. At the time I bought mine, Year One was the only place that had it, and when I purchased the trim they advertise for the '65 Skylark, it didn't fit. I think the two vertical pieces were too short and the bottom corner pieces were totally wrong. I bought the trim they have for a '65 GTO and it fit perfect. 5 pieces in all--two bottom corner pieces, two top corner pieces, one long piece across the top, and two vertical pieces for the sides. Just FYI, 2dr and 4 dr sedan cars have completely different inside rear window trim--they only use 3 pieces and the corners are made into the strips.
