Ok, so here it is: This kit includes adapters, rotors, hardware for mounting, and the soft lines/adapters for connecting to the stock hardlines. All you have to source is the calipers and pads.

























These will work on any trucks that use the 720/hb spindle/hub including the last 2 years of Datsun 620's that ran the balljoint suspension. I'm not 100% sure yet if the '78/'79 spindle has the right mounting pattern for the calipers yet, as they used that morphidite caliper setup.  The hubs have the right bolt pattern.  These will mount to the 2wd 720/hb hub in the stock rotor mounting location. The adapters are mild steel and parkerized which is similiar to gun bluing. Future models will hopefully be aluminum if I can find a cheaper source for stock. The rotors are machined on the inside of the hat to accept the adapter and for trueness. They are 4wd hb rotors and are machined to a spec so it can be recreated in the future.

Price is $600.00 shipped for the kit. They are located in Oregon. I accept paypal for payment, and will ship anywhere using usps.

Just did some diggin into this lately. I was able to look up different years and part numbers on a special NAPA site I have access to, it gives me dimensions of the rotors which is nice.

So:  '78-'83-1/2 used the same rotor and caliper, they list the newer vented rotor and caliper for '83 as well as the older style, so I'm assuming they changed mid way through that year.

'84-'86 used the same rotor and caliper, but in '87 they made the height of the rotor taller by about 3/4" but still use the same caliper through '97 (or at least that was as far as I looked) in '98 they came out with the frontier, so not sure if they changed the brakes again or not.

So to be safe, I think I would make sure to get spindles/hubs from a '87-'97 hardbody to make this setup work.  I'm going to get my hands on the spindles/hubs from the odd years to see what the caliper mount and hub to rotor spacing is, and if need be offer an adapter for trucks of those years.

Just picked up a '78 spindle/hub assy the other day, the caliper won't bolt right up, so I'm making a bracket to work with those trucks.

Doesn't the 300zx caliper already bolt in to the hardbody bracket/spindle? (I'm guessing?)

So what happens when we need new rotors?

The caliper bolts up, but there's no rotor that just bolts up and works with it.  When you need a new rotor, you either buy a machined one from me, or I'll give you the specs and you can get it machined for yourself.  The rotors will last quite a while under normal wear and tear, so I don't forsee you needing to replace them very often.
