If you are going to have a thousand pound lighter (than what?) package you need to remember one thing. Spring rates need to match corner weights.

Just because someone ran a 1" bar in a stockish weighing A body does not mean it's a good choice for one that weighs a thousand pounds less.

Not to mention that wagons have a different, usually better, weight distribution than non-wagons, that will also affect spring rates. Get everything but the suspension sorted out, then get corner weights for us so we can sort out options based on good data, not monkey see, monkey do, suggestions.
