with the u-bolt flip, I had to mock up some new lower shock mounts. They're not entirely done yet, but they're functional. I'm sure there's a better way to do this, but here's what I came up with in the moment.
I cut the old tab off the old u-bolt plate.
then I welded them to these cool tabs that low range had. They're 3/8" thick and they've got a 3" diameter mount, so they fit the tacoma axle housing perfectly.
I drove it down to Orem tonight to pick up my new tires from Bart. It was initially pretty stiff feeling in the back. It felt like a sports car, I could corner without any body roll. Once I loaded up about 150 lbs of tires in the back, it started riding quite nicely. We'll have to see how much it sags when it's loaded up with camping gear.
