Layne,
i have an important question for you ... is this an old trim ... or is it a new one. the reason i ask is they tend to be different thicknesses. i may have one, but i will have to look. i know i have a complete new spare top piece ... but don't really want to cut a piece off of it. i also have a complete new gasket set that i have to put on ... there might be a cutoff piece from that ... but again, its a new / thicker gasket.
