Doing a quick search of 1800 yards this is what I found,
2003 Console Ford Explorer TAN,FLR CONSOLE 5H27 $335
2004 Console Ford Explorer Sport Trac 4DR,GRY,AOT,XLT WI5069 $275
2003 Console Ford Explorer 4DRXLS,4X4,SUV,CHARG RA,AOD,COL 050215 $265
2003 Console Ford Explorer Sport GRAPHITE,COL,COMPARE STYLES 043185 $265
2002 Console Ford Explorer Sport Trac MATCH ONLY 205UPP $225
And there are more....
This will give you an idea basically. I would suggest that it will cost a few more dollars as in your cases you will need/want the mounting brackets as well and the ducting and wire harnesses..
Let me know...
