For those of you looking for a manual transmission flywheel cover to go on your '65-'66 GS, there is a cover from a dynaflow on Ebay right now that can be modified to work. This is how I made the one for my car. If someone needs one and can get this one off Ebay for a core, I can do all the mods to it and make it fit your GS perfectly for $50. Do a search on "buick nailhead" and you will find it.
