I was at the wrecking yard today and saw a 1227303 that looked cherry and ludis's web page shows that the 1227303 is a 1227752 with one missing quad driver. the 1227752 is a 122165 with a short case? Anyone have a clue if a 122303 will replace a 1227165? I'd like to have a spare 1227165 if this will do it, it would be great! Thanks. Mark
