Your 401 will have the larger style water pump that will not interchange with the 305 used in light duty trucks, your type is rebuildable. I've come across these on ebay and there was one on auction just a couple of weeks ago. Fuel pumps will be the same but you'll need the earlier 1960-65 style, I do have a new one of these if you're interested. Pete Chronis Northern Cal.
