Fog light aiming, Need help/measurements

I just got my truck this last weekend and while driving it home I pulled the headlight switch, and wow!!! This was left to me from my grandfather and apparently he liked to use the front bumper in the literal sense. The driver fog points left and the passenger side aims so far up, it's damn near shining behind me.
I know I'm going out on a limb and asking a lot of the members (being new and all) but if anybody can give me measurements as to where the factory fogs shine....I would greatly appreciate it. I'm not picky I just don't want to **** off quite so many people. Any help is appreciated. The truck is a 2000 Harley F150 stock height, minus 2" shackles.

Fog Lamps

Front fog lamps provide a wide, bar-shaped beam of light with a sharp cutoff at the top, and are generally aimed and mounted low. They may be either white or selective yellow. They are intended for use at low speed to increase the illumination directed towards the road surface and verges in conditions of poor visibility due to rain, fog, dust or snow. As such, they are often most effectively used in place of dipped-beam headlamps, reducing the reflected glare from fog or falling snow, although the legality varies by jurisdiction of using front fog lamps without low beam headlamps. Use of fog lamps and high-beams is illegal and disable on most vehicles since foglights can cause your eyes to focus on the foreground rather than down the road.

Use of the front fog lamps when visibility is not seriously reduced is often prohibited, as they can cause increased glare to other drivers, particularly in wet pavement conditions, as well as harming the driver's own vision due to excessive foreground illumination.

The respective purposes of front fog lamps and driving lamps are often confused, due in part to the misconception that fog lamps are necessarily selective yellow, while any auxiliary lamp that makes white light is a driving lamp. Automakers and aftermarket parts and accessories suppliers frequently refer interchangeably to "fog lamps" and "driving lamps" (or "fog/driving lamps"). In most countries, weather conditions rarely necessitate the use of fog lamps, and there is no legal requirement for them, so their primary purpose is frequently cosmetic. They are often available as optional extras or only on higher trim levels of many cars. Studies have shown that in North America more people inappropriately use their fog lamps in dry weather than use them properly in poor weather.
