I've ordered some Ford SD factory 2" blocks off a guy on E-bay, used. I looked hard at all options out there. I think a 3" tall, 3" wide, nontapered block would be perfect. This drops the rear 1 3/4". I never found any.
Superlift makes 3" blocks for Fords but they are tapered. The Fords need tapered blocks, we don't.
I'm just worried 2" won't be tall enough, then I'll be looking for a 1" block to go on top. I know, "don't stack blocks. " I agree but 2" and 1" ain't that much and its considerably less axle wrap than our factory 4 3/4" blocks that don't cause many problems.
I'll post pics when I get them on.
