Gearbox?? & speedo gear

[Slick280z]

Curious which gearbox this is? I was told it was an rb25 rwd gearbox but by the speedo gear location and type has had me real confused, at least I havent seen one like it before online, it uses a short speedo gear or at least thats what was installed when i got it. That short speedo gear had a screw on part to make it electric. It came with the one on the left with the blue cog.

This is what the RB25DET box looks like. Many ribs, much bulk.

 

Anyway, this topic has been bashed to death on here, even given that fact that your gearbox is "unique" to you. Here's an example, where a gearbox that looks like yours seems like it might be a Z31 gearbox. Go down to webber's post.

Appreciate the prompt response. Guess google searches havent been optimal since that post is from 2011 and this is an au site, I tried a variety of ways searching google, even doing image recognition on the photos.
