I do apologize for the delay, but those corvette rebuild kits work like a freaking champ! The directions are spot on, you just need a drill, a grinder or a file, and 1/4 20 tap.
1963-1967 Corvette Vent Window Regulator Repair Kit this is the kit i used, i dont know in this forum if im allowed to share links, but ill let you know as soon as i make my attempt
i have read, that the same style regulator was used in c2 vettes, so i found a repair kit for the vette version, and will be attempting to rebuild mine hopefully this weekend, ill try and post back with results, if your interested.
