Do you already have the parts? If not, I've got a set of used rears springs I bought so that I could remove the lift on my D2 before I sold it. I ended up selling the D2 to someone that wanted all of the add-ons. I'd sell the springs to you cheap. I don't have D2 perches, but I'm pretty sure I've got a set of D1 perches, that should work, but will give you 1/2" of lift of so in the rear. Also, I'm pretty sure based on the color codes these rear springs are from a 7 seater.
