Western Chassis lowering leafs plus what for 6" rear drop?

[WhatWouldSeanDo]

I want to lower my 77 GMC stepside, and am leaning towards a 5/6 static drop.

My stock 33 year old leaf springs are looking pretty crummy, so rather than swap them out for oem replacements I figure why not use the Western Chassis lowering leafs that are made to have a softer ride? WC offers them in 2 and 4 inch drops. I figure I would use the 2" lower leaf combined with a 4" flip kit or the 4" lower leaf with a 2" hanger. I don't even know if either of these is feasible, but if they are, I was looking for advice on which would be the preferred way to go?

I may put a helper air bag on the back for the extremely rare cargo use, but the main goal of this truck is looking good, handling decent and making a damn fine tailgate party truck.

So since my leafs need to be replaced, what's my best course of action for a static drop. I haven't ruled out bags completely, but I don't have any desire to go super low and I have a lot of other places where I could put the extra money into the truck.

Any advice on the 4" drop for the front (I am leaning towards spindles after reading through this forum) is also appreciated.
