I changed the links on my 2000 2500 4x4 with it on the ground in the parking lot of the parts store I bought them at. The truck had about 180k on the original links.
I don't know what part number you need but I ended up using the '99 down link , it was cheaper by half and available at the parts store. At the time the 2000 up was only available at the dealer and double the price, the only difference was the nut arrangement on one end was changed from a castle nut and cotter pin on the 99 to a lock nut and a shorter stud on the ball joint end of the link.
