Well, I took the light-duty D250 stuff out and cut my D350 springs 1-1/4 coils. It was STILL too low! So I got another used set of D350 coils, cut them 3/4 of a coil, and ended up right where I wanted it to be.

The bottom pic was last summer, top pic was tonight. With the relocated rear leaf shackle mount I ended up about 3" lower, front and rear. I also swapped on the brackets and new later-model bumper today.

Ride doesn't seem much different, it ain't no New Yorker! LOL!
