You can buy new ground effects new, or you can get them out of a junk yard (except the front...unless you're lucky)
The LX molding must be removed from the sides the GT Grd effects replace it and it actually has a slightly wider pinstripe slot (if that's what it called?) You will need to buy new door moldings, but other than that the rest is replaced by the kit.
There are also two smaller side pcs that easily go on between the bumper and wheel,
The sides are attached using metal pc of hardware included in the kit (a lip on the side skirts grab onto the hardware.) The bottoms can be bolted/screwed underneath. -same with the sides. very easy to do...I did it with my dad in a back yard garage.
The front bumper is held on by rivets, but you can drill them out to remove the bumper, also find all the bolts that hold on the bumper....takes a while but easy enough. You don't need to use rivets to install the new front bumper, I used bolts (visit my web site to take a look!)
The back bumper is also easy, easier than the front; find all the bolts and install the new one...
There are also two side/back pcs that go between you rear wheel and back bumper, they install at the same time as the bumper, and will slide into place.
If you have any questions, let me know (i've done this to two LX's)
It's worth it! I love my 2.3, but have the style of the GT.
If you are the slightest bit mechanically inclined, All the ground effects can be easily installed, after all; all the cars were made in the same factory, the GT's just got extra body pcs to make them sporty. -they're the same car's underneath.
