Replacement Box 93 xCab 4wd
 

Can anyone tell me what year range and model will fit my 93 xCab 4wd pickup. My box is rusted bad, and I don`t know what other models will fit. I have a chance to but a 95 2wd xCab, but can`t find out if it is interchangeable. I would laso be interested in buying a replacement, but there does not seem to be many of those available either. Any help would be appreciated.
Thanks...
