Headlight lens Replacement

Does anyone know of a place online that shows you how to replace the Whole Headlight Unit for a 99 Honda Accord? I got the over the counter manual at Murruy's Auto Discount and it's not specific enough to even do the job. I even had Honda fax me over something from there interactive network but it is also not very specific. Just shows where the screws come off and just says. Remove bumper. It's a complicated task and I don't want to mess it up.
