My GM900 has a broken spring in the ignition barrel thing - when you start the car, you need to manually return the key to "on" from "start" (otherwise the starter motor just keeps turning). I have seen a second hand cylinder (with keyt) on an auction site - which seems fine. My question is this: how easy (or not) would it be for me to remove my ignition cylinder and replace it with this one? If it's a garage job, then it's not worth the money - but if it's a saturday job (complete with swearing from me and tut-tutting from Mrs H) then I might risk it. It's a no frills GM900s Auto. Thanks in advance!
