Apply the velcro in small 1/4 inch strips to both sides of the grooves on the back of the chin vertically. If I remember there are 13 grooves where the metal grooved screws slide into. SO you'll need 26 lil velcro pieces. I suggest you put the female ends against the chin since it'll pull off there easier. SO now cut 26 lil pieces of the male end of the velcro, remove the backing and place this ontop of the female ends all ready on your bumper chin.
Get a friend to help you carefully apply the chin to the OE spoiler. Make sure your putting it on totally straight. Now while the bumper is there, smack on it like it's your girls buttox. You are trying to make the velcro stick to the OE spoiler. At this point MY chin would stay on without holding on. Draw a line against the OE bumper where the 2 meet and align. Remember the grease pencil can't get into the crease, so add the gap to your final measurement. Now as you are removing the chin make 100% sure that your velcro is sticking to the OE one. It doesn't matter if both ends stick to the OE cover as long as it sticks, it's the measurement that you want. If a few pieces don't stick just do it again.
So now you'll have a greased line on the OE spoiler and 26 little ll_ll_ll_ll_ll_ll_ll_ll_ll_ll_ll_ll_ll_ll_ll_ll_ll_ll_ll_ll_ll_ll_ll_ll_ll_ll velcro marks. At this point you'll only need the vertical measurements and you'll be ready to drill.
Now take all 13 metal grooved screws and apply them to your New chin. Press them all the way in. Now measure the center of the screw to the top of the chin on all 13 locations. I found that although it was frabricated in an injection mold process, there measurements were not exactly even. I found 4 distinct measurements from the center of the screw to the top of the chin spoiler. I thought there would only be 2 since the chin dips in the center? SO I used a piece of paper as a template and punched it through the screw while aligning it to the top line of the chin.
SO now you have the vertical distance from the top of the chin to the center of your screws on all 13 points, now add the little gap that you had when drawing with the pencil and your ready for drilling. Make sure you drill between the ll_ll_ll velcro strips and use your vertical measurement (or template) plus added gapping space and your good to go. DRILL!
Now remove all velcro, remember to clean-off grease pencil markings with a degreaser, and clean and wax the OE Spoiler area.
Again get a friend, and with the screws already place carefully apply the chin. DON"T SCRATCH THE PAINT! The sides will give you the most problems, but it's pretty easy.
Now remove your WHOLE bumper, and apply the plastic nuts to the back of your bumper cover. Then re-apply the bumper and jack up the car. Drill the bottom holes of the chin clear through the bottom of the OE spoiler. Plug-in all "plastic press gromets", lower car and your done. Don't forget to re-wash the front and get a nice amount of wax (2 coats) on your new jowl/chin.
Thanks to Nick-Ny for the help.
