I need a differential ---which one?

The differential on my '80ZX is in dire need of replacement. Problem is, I'm not sure which diff I have. I THINK it's the R180, but I cannot be sure.

 

Will an R200 differential fit easily, and if not what kind of modification/fabrication do I need to do?

 

And what about the U-Joint halfshaft to CV shaft swap? What is required for that?

 

Just in case its important in this, it is a 5speed tranny.

I didn't think any of the ZX's had a R180. I could be wrong though. If you want to go CV, you should have it easy. Get the CV shafts and differential from a 81-83 ZX Turbo, and it should bolt in. If you actually have an R180, then you may need a few more things (like driveshaft).

 

Edit:

I was wrong. According to ZHome.com, the ZX did have the R180.

Can't guarantee this info is correct:

Says you have a 3.54 R180.

 

The R180 rear cover is definitely rectangular - squared corners. The R200 has rounded corners.

 

This page should illustrate:
