Hello,I recently did this swap on my 02 Dakota. Luckily I already had 16 inch wheels. I got the rotors, calipers spindles from a junk yard. I purchased new 03-04 brake lines from Rock Auto. I had recently rebuilt the front end of my truck so I had new bushings and ball joints. I got rebuilt calipers and new pads but was able to re-use the rotors as they were not grooved and in spec. It all bolted up without any problems. A really nice upgrade for the brakes.
I know this post is several years old but I’m hoping this still gets to you. Did you have to buy brake lines to run all the way to the master cylinder? Or do you just need lines from the caliper to the wheel well connection point? Thanks in advance.
