since lower control arm should be level to ground just ensure that is good, side to side and fore to aft, with the rake angle you decided on. also sorta mock up the camber angle before the welder comes out. there is a caster angle to figure too, and more caster is what a lot of guys do because it helps with the gm pump and the ford rack pressure issue whick tends to make the steering a bit jumpy or too easy. increased caster will move the axle back. just a heads up. kinda hard to do without the proper tools though. they look like this

here is a gear ratio/rpm calculator if that helps. seems like you have the tire size you want already though.

joedoh makes a good point to assemble as much sheet metal as you can. you can use a string line to kinda set the levelling of all the panels by the body lines to ensure the front end is at the right height. that makes a difference too. it seems like your number is a popular dimension to set the axle ahead to. can't be too off, right?
