I've been thinking of replacing by building a couple of parts (oil lines, cylinder) on the 550es. Although not exclusive to this model, there are a number of parts that are no longer listed on any of the parts fiches. For example, Part #12 (union bolt) on this fiche:

I can reuse the union bolt, but the parts numbers have some good size information in them.
Is there an online source for the original parts numbers somewhere? Or am I going to hoof it to a dealership, where they might have the original microfiche on hand?
