Have a 73 and a Tuffy. Have had it installed since 03 and never had a problem (except when I lost the key). They make it intentionally difficult to get a new one, which I did not mind. Perfect height for me and would present a formidable obstacle to anyone trying to break in to it. A buddy has one as well. Left his radio in the dash and put a plate over the radio hole in the console and filled it with his switches. Looks cool and is really functional.
