Nice truck.
Since nobody replied YES the kingpins will give you death wobble for sure.
I like the idea of keeping the truck low. I'm actually going to do a bunch of work to improve my Bronco's suspension to perform better, while maintaining stock height.
Aside from the better mileage in a lower truck, and better on-road manners, I also want to avoid all the "fixes" to make it 'right'. I'll avoid steering issues altogether which are the cause of many tire wear issues with TTB trucks. No drop pitman arm, no weird arcs traveled by the short side tie rod, no longer brake lines, no reduced slip joint engagement, no swaybar drop brackets or links, no blocks, the list goes on.
I'm going to trim my fenders at stock height to fit 35's. In doing so I'm going to square off the fender openings a bit, to look similar to the openings in the 80-86 trucks. Then add steel tube flat fender flares like some of the jeep guys use.
REALLY nice truck. Already looks nice, I'll be watching this thread for updates.
