Guys,
I will be installing a set of Z1-900 front forks on my 78 KZ1000.   Also would like to install a dual disc brake setup while I am doing this. 
Here are a few questions:
1) Can I still use the 78 KZ1000 wheel with 4-bolt discs?  Will probably use repo Z1 Calipers (2).
2) I will also need Z1 caliper brackets (L and R)
3) Can I use the 78 KZ front axle?
4) I know I will need a dual splitter for the brake hoses and possibly a larger  front master cylinder
5) is a different spacer(s) required on the front axle?
6) anything else I am forgetting?  
Thanks in advance !

Wheelhop I have some of the parts you may need, splitter, calipers and brackets, brake discs all from a 79 LTD.
I thought you bought both caliper brackets from the guy in Louisville?  

I have both forks. I’ll start exploring.

I have a Z1 and an 80 KZ1000.  Here's what I know.

Z1 forks will fit the KZ1000 triple tree.  The wheel attaches to the forks in a similar fashion but I'm not sure if the brake calipers will match a 78 wheel disc.  The Z1 disc is a 6 bolt.  The calipers would fit the discs if you used a Z1 front wheel.  I think they would also fit a KZ1000 front wheel too, but I'm not 100% sure.  I know that the KZ900 front wheel is identical to a KZ1000 front wheel and that the wheel internals are different than a Z1.  And of course the disc mount is 6 bolt.

The caliper brackets I bought in Louisville are left and right for a 76 and up.KZ..  The bolt spacing that the caliper brackets attach to is different on Z1 forks vs. KZ forks. 
I want to use Z1 forks, Z1 calipers.   

Wheelhop here's some reading about the swap you want to do.
