Now to the work that must be done to get the new parts to fit.
#1 Turn Signals. with the new bumper, the turn signals will come right in the way of the headlight bucket. You will need to cut a right triangle in the bucket to get the turn signal to fit.
That is all the modification required for the front bumper.
#2 Side Skirts. First and foremost lets deal with the vent area. The red is the area which will need work.
You have three options.
First, you can drummel or otherwise "cut/grind" this area down to get the vent to fit.
Second, you can "dent" this area in to fit. I chose this option being a blacksmith part-time I am very comfortable with hammers.
Third, cut the spot welded panel away to expose the correct clip holes and venting area. (Further instrustions in Stealth_E's post)
Use which way you feel more comfortable about doing.
Now one more step with the side skirt if you are NOT using Stealth_E's method, otherwise skirt this step. Just in front of the vent where the skirt meets the door, the skirt must be sanded down about 1cm or so.
This can be done by hand with sand paper, however I used a power sander and it was much quicker.
At this point the side skirts should be ready to bolt/clip up
#3 Door Panels. The door panels will clip right on to the old, however there are no clip areas in the lower part of the door. It is recommended to use double sided M3 tape to hold the bottom part of the door cap on. I did this and it has worked wonderful.
#4 Good News. There is no modification for the rear bumper to fit on to your stealth back-side!
Now follow the reverse of the removal stage, only with the new 3000 bumpers/skirts/caps. Tada! Only one more thing to do... take pix and post here
Congratulations you have your own "Stealth GT".
