i am building (built for mud, not rocks) a 75 blazer with d60, 14 bolt and 44" boggers. i would like to have 14-15 inches of suspension lift. the np 205 driveline angles scare me to death. i have found a np 200 and the math says this one is the way to go. has anyone had any experience's with the np 200. it will be driven on the street also.
