Long and short, I was bored an spent a lot of time an" effort" doing nothing.
I can only think that the combination of numbers is made up by using the different numbers each individual manufacture gave to the same Bosch parts.
The parts being an alternator body, a voltage regulator, a six rib pulley and a eight rib pulley.
I cannot see Bosch having 56 different assemblies for a Crossfire. It does not make sense.
