Do you think it’s possible to change the caliper and e-brake so your not dealing with this dumb design they have on here

You could look at the Chrysler 200 or Jeep Cherokee. I know somebody here did a "poor man's big brake kit" on the front brakes by swapping in the 2-piston calipers from a Cherokee. They're the most likely to be even remotely compatible with the Dart, since they were based on the same platform. That said, they both use an electric e-brake, so good look retrofitting that into a Dart.

😩well thank you guys for the advice looks like I’m just gonna have to deal with needing to spray these damn springs down every so often
What a terrible design

No, you're going to have to periodically rebuild the rear calipers. Spraying the springs is pointless, they don't actually do a whole lot. The problem is that gunk gets inside the caliper from the rear side and causes the shaft for the parking brake to bind and jam inside the mechanism. You have to rebuild the caliper to clean it out, and if it's corroded like one of mine was, it might fail again in a few months (like mine did), in which case you need to replace the caliper. The motto of the Dart should be "That's a pretty neat idea, but too bad about the botched execution of it."

What do you think about me putting this on it

I don't think you can. You need to pack the inside of the assembly with silicone grease to keep everything lubricated. In any case, I'm not 100% certain if it's corrosion or scoring due to debris that damaged the inside of my caliper. All I know is that I rebuilt it last fall and it was binding again by this summer, and I am assuming that is the reason why.
