Got it 90% done
On the drivers side, the bracket seems to need a 3/8 inch spacer between the caliper and the bracket, the passengers side is much closer! Has anybody else run into this?

And for the brake line, I bought two outer hoses for the 300 ZX calipers, I figured since the calipers are floating, I didn't want the hard line into them. They threaded in perfectly, but they are solid so if I disconnect them, I have to do it at the metal line to hose connection and leave the hose in the caliper. Small price to pay for disks, right?

I took a bunch of pictures, and will try to post them on here as soon as I finish up!

Nice work. My shimming for the calipers turned out to be same on both sides. Was the bracket tight to the axle flange on the driver's side?

Looking forward to seeing your right-up.

Yeah, I just figured that the axle tube was gunked up, so I used the grinder on the tube where it hooks to the axle flange and it lined up. I need to find out what people are using to connect the existing brake line to the new hose. It threads in, however it is loose and I am sure it will leak.

As for the drivers bracket gap, I centered the rotor and measured from caliper to bracket, I am going to turn a little piece of sched 80 pipe to .375 and use it as a spacer. Should be able to get it finished by the weekend.

Depending on the amount of spacing, I could cut shims from 16ga and 1/8".. using the same bolt pattern as the caliper bracket. That would allow "fine tuning" the caliper position?

Wow your starting to make an entire kit. Any word on makeing a spacer to replace the back plate on an AMC 20. Same as you made for your 44?

The top half of the bracket would be perfect, the lower (axle end) already fits snug and flush.

if you had a few different thickness's you would certainly be on to something!!

Titan, or anybody who may know. I found the 10 X1 to 3/8 X24 adapter, so my brake lines are now "peachy" I installed the calipers with the bleeder at the highest point, L (I assumed Left for drivers and R right for passengers).
My issue now is with the parking brake. Would it work if I switched sides with the calipers so the E-brake would be in front and closer to the cable, that way they would reach. It looks like they will fit, and the bleeder is still pretty high. Anybody have anything on this?

Someone the other day asked a simuliar question. But they thought about putting the brackets so the caliper is on the front side of the rotor. And swapped the left and right calipers. Not sure if they did that or not.

Ahhhhh.. I see.. the caliper needs to move "outboard".. not inboard. Got it.

Brackets are easy for me. Once they're in CAD, it's simply a matter of pushing a button to produce a stack of them.

Doh!! I forgot all about that AMC spacer. I'll make a note on my work list.. sucks to have the memory of a housefly.

quick update
switched sides...No bueno!!! The bleed screw is below the resivior top... I t will never get that bubble out. I did see where I can re route my ebrake cable to gain a couple inches, and that should do it. If not, I will remove them and re-place the brackets forward of the axle like Rob did. I would prefer them aft of the axle due to rotational force, however since it isn't really a sports machine. that may be my best option!

I am surprised that you needed the adapter. The hard lines I made (which were the same size as the stock ones) connected right up the hoses coming off the caliper. But our hoses do look different. Could be a change between the earlier and later model 300zx brackets.

As for the parking brake, I wasn't too concerned about the cable going below the axle because the stock cable ran to the lower part of the drum. My plan is to route the cable under the axle and secure it to the part of the drum backing plate I left in place. I just need to finish the measurements and figure out how long of cable I need and I wanted to have BESRK's brackets on hand for that.

If you do decide to move them forward like Rob, be sure you switch sides. I noticed in his pictures that his bleed screws ended up on the lower side of the reservoir (good catch by the way )

I moved them back (aft of the axle) and they are on the left and right side accordingly. I am going to switch the passengers side ebrake cable to the drivers and get another one for the pass side a few inches longer. We are going to find a suitable sub today at the parts store, I will post up the part number once I do.

The hard lines on mine were 3/8 24 and the holes in the caliper were MM 10 X1 They will thread in, but kinda loose and I didn't want a fail point in this system. Ricks Perfomance shop had everything in stock so it was pretty effortless, just had to order one fitting, should be here today or early tomorrow.

I cut the flange off of the old axle seals and used it as my spacer instead of cutting my drum backing plate. They were both within .007 of each other.

I was thinking of that but was not sure of the size. Those are cheap if I remember correctly
