Install...how do this?

[tofubento]

Okay, I am accustomed to 240s, and dropping in my LSDs...so never learned much about installing anything in that department.

So, maybe some one can link me to an article or help in this thread...but how would I go about installing this set up :

( that is only an example ) Would I be better off going with a drop in such as a kaaz or obx?

Any help would be great.

drop in is much easier. you dont want to mess with shims and stuff. also i think that is a small case ring and pinon.. not sure what you have

Speaking of drop in, I called some places that I know have diffs, and I was told that a 4.10 diff would make me run around in 5th gear going 45mph...due to having a 325, and not an IS or anything coool like that. I am still learning gearing but is that 100% correct? After checking bits out on : http://www.csgnetwork.com/gearratcalc.html , I think he maybe correct. Any help would be great.

What gearing do you want? You can just buy a complete 4.10 LSD diff and swap it in. They're not too hard to come by.

I am not 100% sure , but its for a daily that I want to have some better traction in the snow as well as just for some backroad driving.
