328gts 1988 ignition switch

My ignition switch needs replacement. Looking through past threads, BMW part 61 31 2 682 120 from a 2002 model was identified as a a replacement. Has anyone had experience with using this part as it is available while the Ferrari part appears to be unobtanium?

 

I now think it is a mechanical problem. Initially, if I fiddled the white wires behind the switch the car would start. That no longer being the case, when I now turn the switch to the three position I don't feel the spring action and it won't start. So yes, I now think its mechanical. The long bolt that locks the steering wheel may put too much pressure on the mechanical side of the switch. Once its disassembled and we can fix the lockset if that is the issue I will also replace the electrical part with the BMW component.

 

Dave,

I also have a 400 and I know that switch is identical to the 2002 switch. What first tipped me off was that the 400 key is identical to the key I had on my 2002 many years back.

 

That's it!
