How do I rip models from a ps2 disc and port them to gmod?

It’s most likely that I will not get any help at all from this forum, but I’m gonna try anyways. Can someone please tell me how I can rip models from a ps2 game and port them to Garrys Mod? I think I’ve gotten the rip from CD part right, but idk how to port it to garrys mod, and I’m not too sure if I did it right or not. I’ve seen it done with Wii games before, so it must be done with ps2 games as well. So can anyone help me out? ANYONE?
