Probably true Dirty. In the USN on submarines, probably the RCN too, they are used everywhere to secure equipment to bulkheads because of the vibes, and they work well. I grew to hate them, but with respect. They were always called distorted thread nuts, thus I've always called them that. Who, WTF was Stover?
How's the printed flex circuit foil look on the rear of the cluster? All nuts tight where it connects on the studs? No tears, open traces, torn foil? Inspect it carefully....
Depends on the Comanche. if it were a Renix, I'd flip it. If an HO I'd swap in rear disks, junk the rear end if it were a D35, and beef up the suspension a bit with ZJ and OME parts.
Guys that like drum brakes also like carburetors, 6V positive ground electrical systems, Lucas electrics, AM radios, mechanical fuel pumps, hubcaps, roll-down windows, generators, faux wood paneling, bench seats, and Renix ignition systems.
That's the problem - maintenance. Drum brakes are maintenance intensive. School buses have mandated scheduled inspections and maintenance programs, and with proper maintenance drum brakes can perform satisfactorily. Unfortunately that's not the case with 99% of the other drum brake junk rattling down the road. Some degree of skill is required to eval drum brake condition which the average Mom and Pop don't have. But any moron can eyeball the caliper pads and easily see they need replacement. Can't do that with drums. And in states w/o safety inspections, properly serviced and functioning drum brakes just don't happen.
Brakes are the second leading cause of accidents due to mechanical failures (defective tires are first), and a large part of brake failures are caused the junk still running around with defective drum brakes.
The way it's set up now you have no worries with the driveshaft operating angle. You can always get an angle finder and measure it.

Love the rear rolled pan if done right like Earl*t's above, but sorry, the round headlamps look like crap on an MJ/XJ IMO. Our main fab guy Krusty was thinking at one time of building an MJ bolt-on rear pan, but I don't think anything ever happened...
Assume you still have your original 30+ year old sagged-out rear leaf springs too? The "chevy lowering shackle swap" is a cheap temporary band-aid attempt to restore OEM ride height. To do it right, replace the tired rear springs and it'll jack it up an inch or three. Then use fresh coils and spacers up front to level it up.
Unless someone added an external, there's no filter. Did you "bleed" the new pump after filling it with fresh fluid? You bleed it by starting it up after installation, then turning the steering wheel stop-to-stop in place until the reservoir stops bubbling air. What are you driving?
