Hub Info

The best hubs are from the 10/82 - 11/85 Datsun 720 2wd pickup.  They allow the small center hole rims to be used.  The 620 disc hubs and pre-10/82 720 hubs will also work without modification(they are the same hub).  If you cannot find a '84ish 720 for the parts, you can mix and match parts a bit.  The correct Hardbody(D21) rotor will bolt to the back of the 620 and 720 hubs.  On the 620 and early 720, the hub is the only part you can use. The rotors and calipers will not work.  On the late 720 and HB, you can use the hub with large center hole rims, or the hubs can be machined to fit the smaller center bore on the older rims. 

****UPDATE!!****
Hub sourcing:
(This is the same info for the Toyota 5 lug hubs.  They also have the Nissan 6 lug hubs, but only the newer versions that need machined for the smaller center hole rims)
Ebay is a typical source for these hubs if you don't have a local scrap yard that has them available.
I'll provide this info as a possible source.  I've spoken with Danesh Mahram directly on the phone and he's easy to work with.  He has sent hubs directly to me to save the customer the added shipping cost.....but keep in mind that I'm going to charge for the cleaning and race removal.

​Parts of this vid look like it was shot through water.  That's because youtube decided it was shaky and "fixed" it even though I told it not to.  You either get a jumpy vid or a woosy one. LOL  Oh well.

I’ve used these before from McMaster-Carr.
Part #: 95735A631
JIS High-Strength Steel Flanged Hex Head Screw
M10 x 1.25 mm Thread, 30 mm Long
https://www.mcmaster.com/#95735a631/=1b15w9c
 
They’re fully threaded, but they’re 10.9 class.....equivalent to grade 8 SAE bolts.  I’m pretty sure the flange cleared the hub when fully threaded in, but it may need just a bit of clearance.  If it does, you can spin the bolt in a drill and file/grind a bit of 
the flange off.  It won’t need much taken off....if any.  Make sure to use a 10.9 class split lock washer too.  
The shipping from McMaster is always fair, but you won’t know what it is until after they ship it.

Cap info

I'll try to get better/more info here, but for now, you can find the cap part numbers here....
