My truck is a 2003 dodge ram 3500 5.9l diesel CUMMINS 4x4, with 248k km/154k mi. gear steering and solid front axle, quad cab. Laramie i think? its got leather and power everything alpine stereo

Im new to the ram world and this truck needs tlc but i cant even figure out which ball joints i need...
i tried online, moog live chat, called a few part stores but i keep getting different part #'s when i ask for a basic moog set for this truck. I really want to fix it myself and not have to bring it in much.

Please, can anyone shed some light on this situation for me? and/or anyone know which moog part #'s i need for upper and lower ball joints? This would be most helpful and i would be forever grateful.
