Lowering a 3/4 ton, Help!

[Mad Viking]

I'm just looking for some suggestions to point me in the right direction. I have a 71 Chevy 3/4 lwb with leafs in the rear. I will be getting 17" rims with low profile tires. I want to do either a 2/4 or 3/5 drop that would provide a good ride and allow for the occasional load heavy load and doesn't cause the ass end to scrape the pavement. I've read and am still reading all sorts of builds that cut coils, use drop spindles, flip the leafs, replace the leafs, install airbags, etc and it's become quite confusing. Since I don't have the bankroll to try all these methods, I was hoping that I could get the forums two cents or someones finger pointing in the right direction. Thanks.
