open diff to lsd really confused
 

hi

i have a 91 240sx .. it had an open diff that originally came with the car.
i bought a kaaz 1.5 lsd and had it installed in the original pumpkin that came with the car.
heres the problem

my 240 has the 6 bolt output shafts and axles.

i want to convert to 5 bolt axles and out put shafts this way i can use the 300zx axles as an upgrade.

what type of 5 bolt out put shafts can i put in my rear end that will not affect the 1.5 lsd?
