Differential questions

[m3f_MegaJP]

I am considering the differential swap in my 95 automatic. So far I know that I have a 3.23 LSD with 4 bolts. Some questions I was hoping to figure out are:



1. What are the models that carry the 3.91 ratio Limited Slip with 4 bolts? (525is Ive heard)



2. How much does should this cost?



3. Is there places online you can buy it?



4. How much can I sell my 3.23 for or is anyone interested in it?



5. Can I do it myself with the right tools?
