Ran into trouble putting in LSD

[574-240sx]

Ok heres the story. I already posted this in the technical page and recieved NO help. Friday night i took out my open differential and i was going to swap in just the LSD Differential. The differential is out of a 180sx from japan. Do i need JDM axels or will axels from a S14 (ABS, 5 Lug) work with the LSD. The stock passenger side axel fits perfict in the LSD, but the driverside axel looks like it needs to be about 1 - 1 1/2 inched longer to fit in. I need help today because i need to have my car by wednesday. So i have to order parts first thing monday. Nick
