I was contacted yesterday by a guy I know that runs a shop that builds manual transmissions and he recently acquired an original 65-66 GS close ratio 4-speed transmisison. He said all the gears and shafts in it look to be in great condition, but that it will need to be freshened up with new sliders and synchro rings. These are getting really hard to find, so it is a good chance for someone to grab a spare or pick up one for a conversion project. He will take $500 for it (really good price for one of these). Post here and send me a PM if you are interested and I will get you in contact wih him.
