tools need to remove driveshaft 1988-2003 Dakota/Ram 1500 ?

No, that's quite a range of possible rear yolks between years and body's. Some older ones will have the saddle type but could have Ethier a 7/16" or an 8mm (5/16"). Or they could have a non saddle type with 9/16", 13mm, or 15mm bolts holding the 2 piece rear yolk together. Or if it's 02 and later could possibly be t40, or t45 bolts on the 2 piece rear yolk.
