What is the production date of your 79? It’s on the tag in your door jam.

How sure are you that your front driveshaft isn't bottoming out? Maybe remove it and test drive without.

That's definitely and interesting though, but it flexes really well off-road. I tend to think its more of a shackle angle/crappy shock and maybe stiff spring problem. In extreme conditions it works pretty good. Its the non extreme conditions where things get violent.

I have no idea what springs you are running. Looking at your pics it appears your shackle angles are nearly vertical. It looks like your frt shackle has a couple extra holes, if you move the spring to the next hole up will probably give you a better angle. This may effect the compression on the frt driveshaft. You need to make sure the d/s doesn't bottom out on the t/case. On the rear you could make a shorter shackle to get a slightly better angle. Removing a leaf in the rear may be a good option instead of shortening the shackle. That will give you a softer rear spring and probably a better shackle angle.

the "rough" country springs before - just didn't know I had them.

You don’t. Those are not Rough Country’s.

Oh boy... Welp, want to take a guess on type? There are 5 spring total (front and rear)
