I'm not getting it. My late 99 has has arms on it and so did my friends early 99. As far as I know neather of the truck were replaced with 01 cupholders. But I can only conferm for as long as we have owned the trucks.
I didn't like the fact that I only had 2 cupholders, I found on ebay a tray piece thing that slides in the centerconsole that has 2 cupholders and a pocket. Probly the best thing I bought for my truck.
