Very cool. Keep us posted on how they hold up. Did that post have any specs on them? Lumens, temp, etc.
I was able to get the 9005s from superbrightleds to fit into my housing, no modification. It took a little patience and trial/error, but they fit.
These bulbs let you adjust both the base and the heatsink, so you can position them perfectly inside the housing. When I first went to install, the opening was too tight for the bulb to twist-lock into place. So I was able to loosen the three screws on the back of the housing, get my bulb set in place, and retighten.
(If you choose this route, remove both housings from your truck, take them inside and put them on a bench or other work surface with good lighting. You'll never get them in correctly and might break something if you try and "quick install" them like they are standard bulbs)

I was also able to get these H11s to fit for the high beams as well, no modification. Again, tight fit, but it worked. These are GREAT for the high beams. (Typically I'm not crazy about putting no-name bulbs in my truck; but I very rarely use my high beams and these seem to work really well)
