Here's a crude chop of one of those pics you posted, the angle is a little weird to properly show it but it should be apparent why the inner tie rod mounts should be moved outboard. I'm not saying this to rain on your parade or soemthing but if you build it as close to perfect as you can now that will save you a lot of time when measuring bumpsteer with dial calipers, to be able to do that you already must be pretty close to where it should be. Otherwise you'll end up redoing it many times. The ideal tie rod length can easily be deter mined just by measuring under the car, err on the short side because there's plenty of adjustment in the tie rod ends (thread)
I know it's a rough sketch but this does show why the rod ends should be moved outboard, not take a look at the steeroids bracket. I can't tell exactly from the pics or measure it but it sure looks like they either have it correct or very close.
