Ok, well I figured I'd give it a shot on one of my extra headlights. I was surprised how easily the headlight comes apart. I put it in the oven at 250F for 8 minutes, on a piece of cardboard. Pulled the lense off with a putty knife and a straight edge screwdriver. There are also 2 #15 torx screws to remove. The aiming bolts are a #8 socket.
The bulb shield is removed by squeezing the two prongs of the shield, and unsnapping it. No screws.
So my first step has worked well, next I will be mounting the projectors probably on Thursday.
As a side note, I plan on adding a raintracker automatic headlight and wiper control system as a part of the HID system. Hopefully integrating the stock Sequoia light stalk that has the "auto" switch.
