make it easy.. lowering a '72

[gintaras]

Hey, i am fairly new here, I'd like a sportier and more agressive looking ride in my '72 LWB
I don't want to cut anything up at all, the truck only has 69k miles on it and is rust-free, so i want to keep everything reversible.
With that in mind, I think my only option is a mild drop, spindles and springs in front, flip kit in rear? or perhaps just springs in rear?

I would also like to still be able to haul things in the back, like furniture and such, as well as be able to tow a trailer.

So.. like the topic states, what is my best bet for this? Looking for a 4 or 5" drop up front, 6 in rear, maybe more if it is easily done.

Thanks!
