I have a 1973 911T with an ignition key that is so worn it almost has no teeth. I had a locksmith cut 2 extra keys off the old key and he said the existing key is so worn he could barely make duplicates. He didn't charge me. I currently have the dash disassembled for restoration so now seems the logical time to replace the steering lock and switch assembly with a good used lock/switch off a later 911.

I think I can manage to remove the old lock. The question his whether my wiring harness will plug into the later model ignition switch that comes with the 1987 steering lock. Will a lock/switch off a 1987 911 fit my 1973 switch wiring? Or should I retain my existing switch and install it on the 1987 steering lock? any advice would be appreciated. Thanks
