32dp worm with Worm Gears Component Generator

[etfrench]

What are the magic numbers to enter in the generator to create the following 32 dp worm gear and worm?

Gear:
120 teeth
14.5° pressure angle
4.08° lead angle
3.75" pitch diameter

Worm:
4.08° lead angle
14.5° pressure angle
0.438" Pitch Diameter

I'm far from a gear expert but here are two solutions:

Forcing helix angle

Forcing Pitch Diameter

Well, those are solutions, but neither is anywhere close to correct.   I've tried manipulating all of the various settings and I can only get either the helix angle or the worm pitch diameter correct.  Never both at the same time.   The closest I've come is using metric settings instead of imperial. 

I need to make the gear to match a purchased worm, so all of the parameters must be correct.

So, no one is willing to reveal the secrets of creating an imperial worm gear with standard sizes

Here's the worm I need to mate with the gear.
