The bushings are too long and contact the shoulder of the Gibson Green Keys. The Genuine Kluson's (Adrian got from a TTR member off a Gibson upgrade) and the Gibson Green Keys have a slightly different screw spacing too....
Gold Grovers are the only other tuners I have on hand...they would work but wouldn't look right....
