You're going to want to build some sort of chassis table (a couple straight and square beams with some supports welded between them) this will be your reference point for square and ride height, it also allows you to tack to the table to try different ride / frame heights.

I have done it on a truck with a true frame off of a concrete floor, but it is way more time consuming / frustrating.

basically the car is completely taken apart and cant move is there a way to do this in its current state accurately?

6-8 jackstands, a tape measure, a level, some chalk, a plumb bob, and a sharpie.

Are you doing a cage as well? I assume it is a unibody?

These measurements obviously won't work for you, but the process is the same:
