NO SENDY
i got from '95 J30...and my car is a '95 S14...as long as you can get the years the same..its a DIRECT SWAP...no covers to switch..

i dont have $$$ for mechanical/clutch type..and i from what research ive done..VLSD is the most reliable in the long run..i am running a NA KA24..so i think this is more than enough..considering it was being driven by a VG30 in its previous life

i am sure 95 and up J30 has the tri-spoke 6 bolt axle thingys..
and '91-94 should be a 5 bolt star..i think thats how s13 is

everything swaps over...less of a headache than Z32 differential
