gregs configuration.scad setup questions

I'm getting ready to print up [www.thingiverse.com] & [www.thingiverse.com]

I got the newest files from Gregs [github.com]

But now I'm a bit confused. At this time I have 2 questions (sure to be more)

1. I am using SAE vitamins (5/16" smooth & 1/4" ACME) with my SAE Prusa v2 kit from makerfarm. In Gregs "configuration.scad" I see:

// PLEASE SELECT ONE OF THE CONFIGURATIONS BELOW
// BY UN-COMMENTING IT

// Uncomment for metric settings
// METRIC METRIC METRIC METRIC METRIC METRIC METRIC METRIC 

include metric.scad;

// Uncomment for imperial settings
// IMPERIAL IMPERIAL IMPERIAL IMPERIAL IMPERIAL IMPERIAL IMPERIAL 

//include sae.scad;

But there is no "sae.scad" on his github page?


2. I also have GT2 belt and pulley setup. In gregs "configuration.scad" there is:

//T5:
belt_width=6;
belt_thickness=1.5; 
tooth_height=1.5;
tooth_spacing=5;

////MXL:
//belt_width=4;
//belt_thickness=0.6; 
//tooth_height=0.6;
//tooth_spacing=0.08*25.4;

I have GT2 belts, can I just create a new set for GT2 like:

//GT2:
belt_width=6; 
belt_thickness=; 
tooth_height=;
tooth_spacing=2;

If so, could someone tell me what to measure for the belt_thickness & tooth_height.
I'm guessing it would be (total_thickness - valley_thickness = tooth_height)
example:

(total belt thickness = 1.65mm) minus (valley thickness = 1.20mm) equals (tooth height = 0.45mm)

Did you ever find the sae.scad?
Could someone point to it?
Thanks
