How do I edit this the best way? I see the redundancy but the point here is to give the extra information. Do I just remove the link?..

Maybe post the extra info as a comment to his answer, why not?

I've seen people post add-on answers elsewhere so I figured it would be fine here - especially since when I started searching there was no answer yet

Okay, but in that case just edit your answer to explain that you're posting this to add some context and don't say "this is the **real** part" because we already know what the real part is.

Oh, with that I meant that while this is the specific part, it is useful to know that it is not a standalone piece. Not good with words, will try to reword it.

I disagree with mindstormsboi here, your answer is just as valid as the other one. Also your answer in original form was fine.

827 Vehicle, Tractor Chassis

870's page mentions it has extra parts that it is used with, and 827 is the complete assembly (steering wheel + mechanism).
