LSD for a 323 GTX

[mathblaster]

Does anyone know what year Miata LSD will fit in a 1988 323 GTX?

I think any 1.6L rear will work, but don't quote me on that.

1.6L rear

Can I use a certain year of RX-7 lsd?

I've been trying to find the actual rear diff ratio for the 323's rear end. I've heard that the 1.6 Miata's rear will work, however, I've also heard that the GTX's rear diff is 4.10:1 whereas the Miata's is 4.30:1. Thoughts?

The RX7 uses a 7" ring gear while the Miata's is 6". The gear carrier is not interchangable.
