Drop Down DVD Install '98 Jeep Grand Cherokee

I've been scouring the internet for days and to no avail looking for someone who's published a step-by-step installation of a (ceiling mounted) drop-down DVD player in a '98 Grand Cherokee (Laredo). I did find this site in the process and am happy to have found it. Does anyone out there know of a posting on this with pics and/or can anuone direct me somewhere that I might find? Thanks
