This varies on the early BDRs vs. the later cars. They began stepping up the size for added strength. I believe you have an early car though and Mark has a later car.
No need for the tank to come out, try and keep it to a minimum of work.
You should not have any trouble picking up a 3.46 LSD all rebuilt for under $1,000 + shipping. I would consider a more aggressive gear myself, but you probably have a preference so I won't preach.
