Keep in mind that I am a welder, but I used a set of fans I pulled off of a Cadillac DTS. I made SST brackets for the top and bottom of the fan, and had to do a little triming to the cadi shroud, (just some bolt stand offs but the width is a perfect match, although the height is about maybe 2,or 3 inches shorter) to get it to fit rite, but I love my set up. They are quite and move a lot of air. If your going to buy a kit, the flex-a-lite is grate, but expensive and kind of loud. Here are a few pics of mine and a link to my write up. Just click the link for my write up on what and how I did mine. They have been on my truck for about 2 years now, and I have never had an issue with them.
