I have almost the identical truck, a 99. Yes, they had distributors up till 99. Mine has the 360, very good motor I think. I’ve heard of many going for a lot of miles. My only complaint is that they are so big, every mechanical job is a major undertaking. The big dodges of that vintage are notorious for steering play, drive down the road a bit like a tractor. There are after market kits to stiffen the front frame and steering. And from what I hear, leave changing the ball joints to a garage, way too much work.
