Been thinking about doing this on the 300SD as preventative maintence. My tumbler looks as though it has been messed with before and it makes me weary.

It works flawlessly every time but I KNOW how much of a punk those things can be to have to fix if they don't rotate.

I need a new ignition key anyway...mine is flunky and short (PO lost the rubber part).

Is a 81 300SD supposed to have a non-high security key for the ignition? Cause mine isn't...(doors are though)
