OK, I am intrigued--why LSD? Are you planning to use this car regularly in the snow? For occasional use in the snow, I would just recommend chains.

The usual 3.54 gears will have you turning 2500 rpm at 60, 2300 if you have 3.23 gears.

A 56 axle will bolt in easily except for changing the spring perches. Then you can get a 3.07 gearset which will yield about 2100 rpm. This is all a lot of work to save 400 rpm. Perhaps I don't grasp what you are hoping to achieve.
