I did a retro fit on my truck too, made a nice difference on the drivability at night, got 4300K HIDs in it. The 7" round headlights on mine were a bit of a pain, I ended up buying a total crap set of chinese round headlights, making a jig, cutting them around the edge straight, got a flowerpot, stuck the bottom half of the light into the flowerpot with tec7 and stuck the lens back on, it earned me a bit more depth
The ones you need are the H1 bi-xenon, they come with a h4 adapter plate. You take the front lens off the headlight, put the projector in from the front, and put the adapter plate on the back, and tighten it down. The adapter plate has little tabs on it in the same pattern as a h4 bulb, so it locates the projector in the correct orientation
