I found this, and I think the concept is pretty much the same,

Bake open the headlamps,
test fit the projectors,
Custom make a bracket,
Custom make some bezel/shrouds.

You also need to mount them ABSOLUTELY perfect to mount them perfectly so that the AIMING is dead on.

Here's the link, I know Goonz is going to yell at me for this, but if and when I attempt doing these, I will put up a HOW-TO w/ pics. Okay guys? Uh... if someone has taken pics of their projector mounting, please chime in and POST THE BLOODY PICTURES... TIA CEG.
