So I've seen these things (and I say things because I don't know what they are called) on trucks in pictures and occasionally on trucks on the road. I guess they would fall under the category of like aero kits or wind deflectors. My best description is that they are triangle shaped body pieces that fit in the 90 degree angle where the bed meets the cab. They are not inside the bed, rather they are mounted on the sides of the bed one on either side. I believe they have them on racing trucks and I've seen a 90's model Ram 1500 sport near my area with them. I will try to find a picture of them to post. I'm just trying to figure out what they are called and/or where I could get them. Any help is appreciated, thanks.
