recently sold my 2004 dakota, 4.7, 3.92 gears with the factory LSD, had 271,000 miles on it. Found a 2007, 4.7, with 51,000 miles. I love the truck, but its got 3.55 gears, not LSD (also no heavy duty cooling, and rear brakes are drum, not disc like my last truck). I miss the 3.92 LSD when I retrieve my boat at the launch ramp, and when I back it up my steep driveway. Can I buy a 3.92 with factory LSD at a junk yard (does it matter if off a 1500, or Durango, or?), and just bolt it in, and do I just change the speedometer drive gear, or is the computer involved some how? I am open to other suggestions as well.
Thanks.
