I ordered brushes and also bought this one on ebay, that doesn't show any brand.
It arrived and came in a Transpro box and also says Transpro on the part. Here is
a bit about the US based company or maybe just a US distributor:

I was pleased to see that it was not a completely no-name part.

The two that list an OEM bosch number both list 1 127 014 028 that Chuck W provided
so I'm going to order that one, probably from Amazon for $7.43:

When I tried to order these brushes on Amazon the shipping time was very long,
like 3 weeks and I could not find where, what country, they were shipping from.
So I bought them on ebay from a company in Ohio:

We installed this a couple of weeks ago and it is working fine.

Is there a wiring diagram that shows how the wires are routed in the car?
I'm wondering if the large red wire on the back of the alternator goes up to
the battery terminal, starter, or fuse box.
Edit: It goes to the starter according to parts info.
