Will the ignition cylinder and switch interchange on all years of the 750 and/or will other years/models interchange with a 2005. The key cylinder suddenly stopped working and would only turn partially to the off position. After taking it apart it appears as though the PO had been into it before. One screw on the switch was missing and the remaining one is bent. also the plastic around the slot on the top of the switch is chipped away. Is it possible to disassemble the key cylinder and try to see what is stopping it from rotating all the way to run. although broken and missing a screw the switch still functions.
