Wow, yeh that is an very old article, 2003, making it 15 years old!
Okay let's see what we can do here.
For, Ghost Recon Model Pack by Piggyson please try this and let me know if you think it's the correct file. I have also reached out to Piggyson, let's wait and see if I get a response!
Or try this page - is it any of these files? http://www.woody2000.com/download.php?list.22
It is frustrating that back in 2003 I never thought to start mirroring these files. I only started doing that years later.
