I understand the money thing believe me.
Just get the front end aligned after installing springs.
With 5" drop in rear, you're gonna want the shock relocated. It's not going to be near as effective at that angle.
So, besides the springs, you'll need front and rear shocks, shock relocate kit for rear, adjustable panhard bar and some very short bumpstops.
What you can do, is install the springs and shorter bumpstops in rear and check your clearance. You can always add the frame notch later. CPP's got the bolt-in C notch. You just cut, drill and bolt on.
Where are you getting your stuff from?
