So far (knock on wood) the car has been pretty reliable.
Unbeknownst to me the circa 1987 differential bushings are diehard readers of LocostUSA.com. Apparently they plotted against me and decided to rub my previous statement in my face.
A good launch on hot slicks and the differential was free along with all of the internals of the driver side halfshaft CV joint:

Everything is repaired and the car is back in action but it makes me kick myself for not replacing them during the build. Then again they were absolutely awful to remove* so that may have been motivation enough. Fortunately the aftermarket polyurethane ones went in much easier.
I also noticed some excess movement in the engine. I didn't have to look very hard to find the cause - when I removed the top bolt of the driver's side mount, part of the mount came with it.

There was also some cracking near a weld at the bottom of the mount. I welded the cracks as a temporary measure but I'll have to design a new mount one of these days. There are fewer constraints in that area now that the stock intake is gone so it should be pretty easy.
I'm also going to paint the new ones gray. The black paint made it impossible to spot the crack until it was huge.

Very old news I missed, but you are missing the stop washers. They are used on the miata also.
