Answers.Text: 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.

  The specific part (870) is identified in the other answer, however it is part of an assembly with its own part number:
  
  <https://www.bricklink.com/v2/catalog/catalogitem.page?P=827#T=C&C=3>
  
  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).
  
  This page details what other parts are needed to complete it.
  
  <https://www.bricklink.com/catalogItemInv.asp?P=827>
  
  870 is the base in the picture, and 871-874 are the mechanism pieces.
