I have a nice rear clip that will work on your 1965 GS, sedan, coupe or convertible. Yes you have to trim some metal off above the where the chrome goes on a regular Skylark, but you get a better taillight section, wheel wells, lower quarter including wheel well opening metal and a solid trunk floor all the way up to the back seat. All of this for $500! I’ll throw in the trailer it is sitting on for $350, and a free trunk lid. It has to go soon or it will be cut it into pieces, I need the room. I am in zip code 95453 if you want to Google the distance. I don’t have access to a forklift and no shipping facility within 50 miles, so pickup only.
