ok i have some good news and some not so good news. 1st the good news. i found side to side electic windows and up and down versions. the only issues (this is the not so good news). the up and down version if you don't want the whole window to slide down you'll have to use a explorer sport trac rear window as suggested by solow93, but it's just the center that slides down (which is found at a junk yard or ebay and modifying will be required). now if your wanting the whole window to slide up and down use a limo partition assembly, they're only about $250-300 for the whole set up minus the glass(which is found at link below and modifying will be required). now for the side to side electric window they make one for the 97+ ranger so yes once again.... (which is found at link below and modifying will be required). i hope this helps some.
