Welcome to Allpar. I haven't had any personal business dealings with that outfit, but maybe someone else here has. I drive a 99 Grand Caravan with the 3.3 and it has coil packs and no distributor. That seemed to be the weakest point on the 3.9 Dakotas, but after a couple of hundred thousand miles and so many revolutions, they can wear out. Sounds like you've got a couple of fine trucks to me.
