Hey brothers, Here you go, this is the way I did it. I hope this helps:
1- I suggest doing one side at a time and get someone to help; it pays off at the end when you are trying to line up the hood.
2-Don?t try to install them on your lunch break. Allow your self a good day to install them. It takes time and a shit load of patience!! The time, effort and patience you put forth will reflect in the end product.
3-Disconnect the battery and take it out
4-Take out your headlights, pull up on the 2 slide tabs lift it out
5-Remove the plastic trim end piece where your windshield wiper mounts. It appears to have a screw, but it is a plastic insert. Pry it up with a big screw driver so you can get to the hood bolts.
6-On the inner fender skin disconnect the horn and a vacuum line (driver?s side) that goes to the fender skin. I removed the wiper fluid box also, but put it back in when I finished. On the Pass side, you have to disconnect the horn, unbolt the black box that sits on top of the radiator over flow container, and just move it out of the way and remove the antenna. I put mine back on.
7-There are like 14 bolts to remove, 6 in your wheel well where the wheel well mounts to the inner fender skin, 2 in your door jam, 1 underneath the truck where the bottom of the fender rolls under, 2 on top at the firewall where you hood hinge is at, 1 at the hood hinge to the fender, 1 at the end of the fender by your grill, behind the headlight. They are all ? inch.
8-The fender should already be ready to come out, down by where your bumper raps around to meet the fender, there is a piece of metal on the fender that you will have to bend back in order to get the fender out a lot easier.
9-If you plan on omitting the fender well and inner fender skin, you can move to step 13, now you can start hack?n away at it. I kept mine.
10-Once you have the fender removed, now you have break 25-30 spot welds. I used a small ?sharp? drill bit as a pilot hole for each, then came back with a bit that was just slightly larger then the spot weld, they are maybe 3/8 of an inch, it made it semi easier. You will be able to use a couple of them for mounting points along the top channel. I couldn?t find a Rigid tapping punch bit like metul munky suggested. It also helps if you have access to a pneumatic chisel. It will save time. Air tools rock!! But I suggest when it come to installing the glass, don?t use air, you might crack the mounting points. Just FYI!!

11-After you remove the inner fender skin and have it cut to your desired height, I recommend a hand held grinder with a cutting wheel on it to cut it. Try to keep the top back mounting hole intact (where it bolts to your door jam) it add to the strength of fender. You don?t need the bottom one; the lower door jam bolt will bolt directly to your new fender. There should be a tab on it. I used the stock metal nut clip off the old fender for that. After you mark and drill that hole, just spread the clip out more (the glass is thicker that the original fender) and slide it on.
12-Now you can mount the inner fender skin. What I did was, I put it on and put the new fender on to make sure I cut it to the desired height (so you won?t see too much of it) in the fender well.
13-Once that is done, line up where you want your fender to be and mark the holes and drill them. A good rule of thumb is measure twice and cut once, opposed to measure once and cut twice. I suggest you try closing the hood to make sure you allow room to clear and the alignment is straight. This is where your buddy really comes in handy. If you kept the inner fender skin, you are going to have to cut a small notch out on the inner channel of the glass. It sits higher and the hood mounting arm will hit it, allowing your hood not to close. You will see on one of the pics, what I am talking about.
14-Now that you are happy with the alignment, bolt it on. Don?t tighten them down yet, try to close the hood and open the door make sure it is aligned and aren?t binding. If it binds at the door, you can shim it with a couple of washers between the glass and the door jam mounting points. If it is good and or you adjusted it, tighten it down and start the other side, same thing.

15-Once you have both sides on and it looks sano, you can adjust your hood so it sits level with the new fenders, they will most likely sit higher. Loosen your hood latch bolts and move it up. Unscrew (counter clock wise) the rubber stopper at each end. Do this until you have an even gap all the way across.
16-The tools I used were just basic tools to include pneumatic chisel and a hand held grinder with a cutting wheel. Hopefully I didn’t leave anything out. There you go, Good Luck. And Roger…….
