Kent,
I have read your manual for the replacement of the steering lock + tumbler and purchased all the parts I need. I have a steering lock from a very well maintained 91 420SEL. Can I use the alarm buzzer from that one for the steering lock of the 83 300SD? It is different in that it allows for one more plug than the one on the 300SD - but the other plug looks the same.
Thank you
Dieter
