OK, the question about B210s.
The Encyclopedia was envisioned as a Datsun 1200 (B110/B120)-centric project.
Here's my take. Most B-series rear-wheel-drive info is good to know for us 1200 owners. So we don't mind it. This includes B10, B210 and B310 as well as the trucks (B20, B120, B122, B140, etc). I have even contributed some information to Tech Section (e.g. the PB210 article).
But remember the Encyclopedia -- like this site -- is mainly for Datsun 1200. So please call it out when you are discussing other models. For example, maybe B210 info should be in another article.
Let's take the "Engine" article. It will focus primarily on the "Datsun 1200 Engine" -- an overview of what that is. Of course information about the whole A series range is good. But that's already in the Wikipedia (and a GOOD article I might add):
Nissan A engine on Wikipedia.
In the Engine article we might mention that B210s also came with A12s and highlight how those A12s are different from the B210's A12. Keep in mind that the
"Engine Swaps" article also has a lot of this info.
In short:
* Keep it Datsun B-series-centric (rwd)
* For non-1200 stuff, break it out in another section or another article if possible
e.g. see the "Datsun 1000" section in the
Canada article. The "Canada" article is mainly about the Datsun 1200 community, but there is a section calling out Datsun 1000 information as shown in the Table of Contents.
