I have a set of disk brakes off of an 05 1500 that I plan on putting on the rear of my 98 1500. I would like to upgrade the front as well. Will the steering knuckle from a 05 fit on a 98? I have a set of 17 inch rims so that is not going to be a problem. I haul a lot and pull trailers through the mountains and the standard brakes are not working out. Like I said I have the rear disk set up just need to upgrade the front. Also need to know if I need to change master cylinder and p-valve because the 98 originally had drums on the rear.
