I mounted a bosch alt. on my car, to my knowledge they all have internal
regulators, I would doubt very much that they had lucas regulators. they
either have 2 posts, one bigger than the other, one for the ind. light the
other for the battery connection, or they come with a slotted plug
arrangement. I looked at a pile of about 100 bosch alternators in a vw
junkyard, none of them had anything lucas on them.
