I replaced one on my 96 and they do bolt on, not snap.
The rectanglar holes are for easier installation or sloppy production tolerances.

 

when I did mine I used a sander and sanded my hole bigger to get mine to fit.

 

Yeah but you already had them, I think the bolts and clips are similar to a license mount, just flatter to fit under the black plastic bumper cover. If you don't already have them there is nothing but the holes in the steel part of the bumper.

That reply was to charlies post btw.

 

Gentlemen, Gentlemen, there is an easier way to do all this if you don't mind fabricating your own brackets. I have a habit of doing things my own way. Sometimes it works and sometimes it doesn't. This time it worked out just fine. I went to WalMart and got some $20 round fog lights. They fit perfectly in the existing holes with no cutting. I don't like to cut if I don't have to. I adapted the brackets they came with and created my own brackets. I did not remove my bumper cover. I again don't like removing anything that I don't have to. I fortunately found two large holes already drilled into the chassis right behind where the fog lamps should mount (the holes are on the body rail in front of the radiator). Open your hood, get a flash light and look in there. My truck is black so it's dark, for a lighter truck it may be easier. Make your own brackets and mount those puppies yourself. This is why I always keep all sorts of scrap stuff lying around since I never know what I will need it for. I used some old scrap metal I had put away for such an occasion. If you really want to see them I guess I could be persuaded to take some pics, but if you don't want to follow my redneck way, then I'll leave you to your OE methods.

 

The thing is that I already have the OEM lights and want to use them. Thats the challenge.

 

If you were talking to me I did not have fog lights.

 

That does throw a monkey wrench into the plan.

If you have the lights and brackets then you have no choice but to follow the steps the other guys mentioned. If you don't have the brackets you can either make your own, or I think I saw the OE brackets at LMtruck.

 

I would just do like I said take off your bumper and take the black plastic the top of the bumper and take off the plastic that you put the lights in and take a sander and sand the plastic till the lights will fit. get some carge bolts and lock washers and nuts to put them on with those. have you and another person to help readjust the bumper when you put it back on

 

dremel makes a cutting wheel for the easy lock bits for cutting plastic, thats what i'm going to use on my dads truck.

 

well thunderz, like helms said it is pretty straight forward but you wanted a diy. my dad has the walmart lights but you'll still have to cut the hole to make yours fit.

this bit in the dremel makes it pretty quick.


i'm sure you can use something else to draw a line like the bottom of a can the same size as your lights but i marked a toothpick and lined it up with the back of the hole and made a series of dots and connected them when i was done. doing it like this made sure that the hole was centered.


when cutting you have to keep the dremel pointed straight toward the truck so it will be nice and even.


after your done with the cutting, use a piece of sand paper to clean the plastic burrs off the edges. pick off as much as you can first then use the sand paper.


hole 1 done


the bracket still needs to be extended to make the new lights stick out of the holes so it'll have a wider beam.


hole 2 done.


all together it took about 15 minutes on each side.
