Jason I'm afraid there's no direction to point you to that's not going to be a waste of money. Every single one of those ebay type aftermarket headlights with 'projectors' in them are built for halogen bulbs. The output is worse than your stock setup because those projectors don't project light better than your stock reflectors. And if you waste even more money and stick HID bulbs in them, you will get this output:
These things are not actually projectors, just plastic molded to look like a projector.
I know this because I made this mistake myself before getting a proper retrofit.
Once again, your options are:
1. Do nothing and buy the best halogen bulbs for your oem halogen reflectors.
2. Throw money in the toilet by buying aftermarket housings.
3. Stick HID bulbs in your halogen reflector housings and glare everywhere.
4. Retrofit.
More info can be found in the 'HID BASICS' link in my signature.

Oh and the only pre-retrofitted plug and play solution out there for your truck is by BFC:

But it's not cheap ... although cheaper than throwing $200 away on crap aftermarket housings.
