I like to do all of my own maintenance on every piece of machinery I own, from my Newholland tractor to JD gator, from my 1999 Honda Valkyre interstate and 1999 Kawasaki 1500 drifter, to my 1999 36. 5 Rexhall Aerbus motorhome etc etc etc--but most of all I like to take care of my pride and joy, my pickup truck; QUADZILLA. I have the differential cover and the transmission pan and both pieces make routine maintenance a joy---compared to the stock pieces. The workmanship is second to none and absolutely beautiful! You'll be tempted to wash both the trans and rear end covers every time you wash your truck! Keep the old covers so you can put them back on when you decide to sell.
My truck currently has 72,000 miles on it and has had only the front brake pads and tires replaced---absolutely nothing else has been fixed or replaced on the truck, not even a turn indicator bulb and it's never seen the inside of a DODGE dealer. Everything works perfectly and at least the inside looks just like new. It's hard to keep the outside looking new when living on a farm in the country! I may keep this truck forever! Take care, Sam
