Dropping a 3/4 ton Suburban?

[SRD art]

Hey all I'm the new guy and have a question about lowering a 3/4 ton 1977 Suburban. This is a new toy for me and currently it sits fairly tall and level and is crying to be dropped. I'd like to go about 3" is all and prefer to use spindles up front for at least 2" of that. I called Summit Racing who I get most of my go-fast junk from and they said they don't have a listing for 3/4 ton drop spindles from any of their vendors. A friend sent me the link to these which sound like a great deal. http://www.airbagit.com/product-p/spi-gm7191c.htm

Now I'm having trouble finding a way to drop the rear. An axle flip would be too much, like I say I want 3" at the most. Any suggestions for me? If this has already been brought up is there a thread link? A big THANKS! in advance.

It isn't finished yet but here's the start of my concept drawing so you get the idea. We just bought the truck, it's mostly stock with a great running 454 and fairly new red paint. Trouble is the clear coat on the paint job is peeling badly on the hood and roof. My main business marketing colors are red and black and I'll be using this as my vendor booth hauler for car shows I attend. In the past I've parked my old booth hauler (my Cutlass station wagon) by my booth or entered it in the show so this Burby's got to stand out and look cool too. I thought I'd do something a bit different and re-paint the top half semi gloss black and run 20" rims to match the body color. I'll post the art again when it's done.
