People usually don't include links to the files they are using unless people IN THE THREAD ask them.
Next time instead of starting a new thread try either reading through the WIPs with the models you want to use to see if they posted links, check the stickies for file links (there will always be links to any file ever made/used by members), or by PMing someone.
If you like the files the OP of a WIP is using, just PM them or post in their thread. Most people will say what models they're using in the first few posts.
