So in order to build a rear setup that is basically a one-off, it requires a bunch of custom parts. There was a ton including all of the laser cut parts (almost 40 pcs there alone).
Here are some of the laser cut and machined pcs.
Rear lower shock mounts:
Axle tube mounts for the Watts, also the rear sway bar attaches directly to this bracket. A top clam shell clamp was also made.
Some of the link eyes in process. I made both right and left hand versions so they are on-car adjustable.

The milling steps to make them, not including turning and threading.
Here are the 3 links and the lower shock mounts all finished up and powder coated.
I went with a transmission mount that was made from tab-and-slot construction as well.
Of course, I made the bell crank for the Watts...and a few spares
Can't seem to find the other pics, but that'll do for now. Should give you an idea.
