This is the best driveline shop in Vegas, bar none. I'm a garage tinkerer and get by doing most stuff on my own, but when it comes to this its worth the few bucks to make sure its done right.
Their prices aren't rock bottom, but they are worth the premium. Most importantly, they are HONEST and will never charge you a dime for something that you do not need.
Head out to LVMS or Apex and you'll tend to notice that nearly every "serious" driveline was built at Dan's.
