Which way to go??

[IndyNova]

So I have my 70 stepside that currently rides on its stock suspension, and wheels. Ive got a set of 20x10 and 18x8 ridlers to put on it, but it needs to come down....a lot...lol I don't necessarily want it to lay frame, but I would like to tuck the rear wheels.to some better susp. components). This will be a cruiser, but I also wouldn't mind auto-Xing it eventually(after upgrading So, since i have zero experience with air ride, and I'm on a shoestring budget, should I do:

Piece together an airbag setup, and If I go this route, what all do I need to buy(other than bags and compressor)?

Use drop spindles and springs for the front and bag the rear only? Again, which components are best?

Any advice or help to steer me in the right direction, is much appreciated!!
