j30 vlsd install question on s13
 

i have a vlsd from a j30 with 5 bolt axles. this is the question is it a straight on bolt on or is it not. cause of the ABS issue of the vlsd. cause i dont know if i have a ABS vlsd. when the ABS vlsd is install on a s13 will there be a gap between the driveshaft and the vlsd. what do i have to do if i have the abs vlsd. i know the vlsd is a pre 95 vlsd and is not the 95 and up version's with the 6 bolt axles. but searching throughtthe forums from club240 and zilvia.net does not explain these questions i'm asking. both explains what would fit but what mod's do i have to make them fit besides the axles. i would like get get detailed info
