90 vert diff ratio?
Sorry about all the different posts but I have so many questions.
Ive looked everywhere and get different answers. What is the diff ratio of a manual 90 vert? heard it was 3.90 on all verts, heard all manuals were 4.10. so what does my manual vert 90. have. and does a N/A 4.30 gear from rx7.com or mazdatrix bolt right in. Need to know bc I want to go with a 4.30 and Kaaz Lsd? Again Please help. It is greatly appreciated, you have no Idea.

Automatics were 3.9, If I remember correctly you should have the 4.1.
The kaaz should 'bolt in' per se. All you get is the diff so you will have to open your pumpkin and replace the diff. You could just call mazdatrix and confirm though, they won't bite.
