Chrysler makes some flat rubber flaps with the neon logo on them, but they have some molded splash guards too. They are molded to fit the neon body shape. The fronts are part number 82300550, the rears are 82300551. The front and rear splash guards are pretty effecitve in keeping out mud and dirt. They are some kind of black thermoplastic rubber which doesn't bond well with paint. Be aware that the instructions and hardware contents are not correct for later model neons, or at least not for the 96 ACR.

While you have the fender liners detached, pull them away from the fender and reach behind and make sure the area behind is free of dirt and leaves that will trap moisture, accelerating body rust. That area is a small pocket formed by the bottom rear of the fender and the inner body. Debris tends to collect in there, and stays wet a long time.

Front splash guards

The differences have to do with the instructions being for three fastener mountings per splash guard, and you probably have four. However, they pack enough hardware and it is not difficult to make do with what is included. You may need to re-use the old hardware on the lower holes because the supplied hardware will pull through the holes in the fender liner and splash guards, eliminating the chance of getting a firm mounting.

Generic Instructions For Front Splash Guards.

1. Turn the steering full left to install left side splash guard and full right to install right splash guard. This provides plenty of clearance.
2. Remove the stone guard, using a T-25 Torx bit.
3. Just above the fender holes where the stone guards mount are two more fasteners that secure the fender liner to the fender.
4. Carefully dig under the head of one and clip it off by using a sharp knife or diagonal cutters. Then do the fourth hole above.
5. The splash guard is supposed to mount between the fender and the fender liner, so thoroughly clean the fender where it will mount.
6. Pull the liner away and fit the splash guard onto the fender.
7. Examine it closely for fit. Don't forget to look from the rear. Do the mounting holes line up? Does its contour match the fender contour when the holes line up? Does it fit right up against the body? If not, you may want to elongate the holes or trim the lower edge of the splash guard. I had to do both.

Existing Hardware Instructions (when using plastic fasteners is not desired).

1. Install the new fasteners to the upper two fender holes. Spread them way open to minimize scraping the fender metal.
2. Locate the splash guard in position between the fender liner and the fender.
3. Install existing screws into the lower holes. Their wider heads are necessary because of the larger holes in the fender liner.
4. Install new screws in the upper two holes
5. Turn the steering the other way to full lock and do the other side.

Alternative method For the alternative method, using the spring clips or thee generic hardware is not recommended for the lower two fasteners per instructions. Instead, go to your local automotive supply store and pick up some plastic fasteners like the ones it is implied you have to clip off with a knife or side cutters. The reason for that is that the supplied spring clips are very tough and even if you do a good job spreading them, they will gouge right through the paint, down to bare, shiny, deformed fender metal, leaving a nice place for rust to start. But plastic, expanding rivet type fasteners should leave your paint intact. The trick is to spread open the existing clips to take them off without scraping the fender metal.

Plastic Fastener method

1. Remove existing fasteners from the lower two holes in the fender. To remove, spread them apart, or bend them open to minimize scraping the fender metal.
2. Go to an automotive supply store and get some fasteners (8+) that closely resemble the ones Chrysler Corp. uses in the upper two holes. Use the hole size to try to get the right fasteners the first time. The lower holes in the fender liner are bigger than the upper holes. Go for the largest size that will fit into the fender holes, since the holes in the plastic can always be opened up.
3. Follow the fastener directions and install the fasteners. Remember, the splash guard goes between the fender liner and fender.
4. Turn the steering the other way to full lock and do the other side.

Rear splash guards

The rear instructions are also flawed in a similar way as the fronts, but they are more straight forward and useful. So, again, read them to get some clues. The splash guards mount to two existing holes that use the above mentioned Torx fasteners to fasten the non metal rear bumper fascia to an under structure that is also plastic. Two holes will need to be drilled for the other two lower mounting points.

1. Remove rear wheel
2. Remove the two existing fasteners, as mentioned in the instructions.
3. Clean the dirt from where the splash guard will mount.
4. Mount the splash guard at these two holes using the original fasteners, which are far more robust than the ones supplied with the splash guards. Don't tighten the fasteners yet.
5. Test fit the splash guard to the contour of the fascia. The holes may not line up when positioned for the best fit. You may need to elongate the two upper mounting holes. Elongate as needed. I used a rough rat tail file and a knife to trim afterwords.
6. For each of the lower holes in the splash guard, use one hand on the inside of the fender to draw the fascia into the splash guard as far as it will go. As the instructions say, get as tight a fit as possible. Mark a drill center.
7. Make sure your finger is clear of the opposite side of the mounting hole. Use a 1/16 drill and drill a pilot hole for each of the lower fasteners, using the hole in the splash guard as a estimator.
8. Enlarge the hole to 1/8 in. The instructions call for 3/32 in, but problems my arise from making it that large.
9. Install two of the "biwax" fasteners that came with the splash guards.
10. Tighten the two original fasteners in the upper holes.
11. Install the wheel and tighten to specs. Tighten in star pattern to 80-100 ft-lbs torque.
12. Lower the vehicle.
