well for the front, just get the cups, and someone here should be able to tell you the cup height you need
and as i know, the engine crossmember will lay before the frame will, so you'll have to Z it to lay the frame flat later on...but you can lay engine crossmember for now. you also have to get rid of the inner fenders
as you know, u need the comp, tank, valves, lines, fittings, etc. etc.
about the gauges, if you get a typical mechanical gauge, you do have to run an air line to them, typically ppl use 1/4inch or 1/8th, i ran 1/4th....but a company called Dakota Digital makes digital gauges where you just mount a sensor in your air system and it'll transmit it to the gauge screen...its quite pricey, FakeEdge had one, i think they run around 2-300bones, but they are awesome
you can go ahead and notch the back w/o bagging it, just make sure you place the notches at the right location, pretty much the axle should be centered when it comes up into it
tank placement depends on what you want, you can put it in the bed, between your framerails in the back part of your frame..etc...where ever you want lol
