I'm looking for a Bosch 0221 121 006 black coil.
It's the one with offset A and B terminals to allow it to fit the multiway connector as found on '74 911s.
Like this
It would need to be cosmetically good and within spec. Primary winding 0.4 to 0.6ohm. Secondary winding 650 - 790 ohm.
May be able to swap for a more popular 0221 121 001 if I have one left, if that is of interest.
Let me know what you have.
Much appreciated
Andrew
