Something else I still have a few of is the regulator brush packs for the earlier Bosch alternators. There was one part number that would fit a couple of dozen different applications. Most of them you could do in situ,just two screws. Last points I did was a mini about 5 years ago. Do you remember the dizzy location on the P305? Pig to get at and easier to remove the whole thing from the vehicle. They always ran great afterwards as they probably hadnt been replaced in years.That had the external adjuster. Regards, Tony
