QD32 is a strong engine, it can definately take a beating
QD32's came in the Frontiers , E24s, Atlas' and Pathfinders
.
avg 650kms on $90-95
the difference with the body parts are
the facelift in the newer - lights, grill, bonnet, fenders
the fender flares are bigger in the newer model
the tailgate is different as well
the older bumper has diamond metal plates at the top rather than the plastic top in the newer
interior/ chassis/ doors/ drivetrain/ cargo box same
manual running hubs arent as convenient but durable
N&M definatley has parts
but ROC in the bamboo is the best place, they'll even find and import the part for ya on request @ a btr price than N&M
seeing that all suspension parts changed you should be in a good place there
you should find out what kind of work the vehicle did tho.........mine is 10yrs old its all original suspension parts without problems or any fuss at all (a lot of offroad driving which turned into casual since im solo. but there's Side B to cut some slack

)
be sure to scope out everything, LH posted some good stuff there
also check the centre bearings on the driveshaft
