I bought some new GM hood springs and seller indicated they were for 70-2 Skylark/GS, but I'm not sure. The part number is GM # 03864680 GR. 8.013. I looked the parts book and could not find them. They have 26 coils & about 8 1/2 " in total length. I think they might be for a larger car or something. Anybody know which GM car or truck these would be for? Thanks
