[QUESTION] Setting char old models on npcs (WOTLK WOD patch)

[Zinematic]

Hello to all. I have a problem with a patch I am doing for WOTLK, which replaces old character models with WOD ones, but npc's textures are messed up, and I can't assign WoW old models to npc's, I've tried some methods with dbc files, but I can't seem to fix it. Sorry if there's some tutorial that can solve my problem, I have looked up on the page, but I haven't found anything. If someone told me a solution for this, I'd be very grateful, and I could share my patch with everyone. Thank you all .

PD: Sorry if my english isn't very good, I'm Spanish .

Something similar was done with Goblins when Cata Goblins first came out before the Baked textures were found.

What was done is that somehow a new model called gobinold was made, and the npcs were tied to them.
I'm not sure how you'd do that here because I never understood how Goblinold was assigned an ID

I did this with my custom patch for 4.3.4 and the problem is I also put the old model for the caverns of time morphs and I have no idea what the caverns of time morphs IDs are to put the player models there and not the old models. Asked around even the guy who suggested this idea in the first place and he ignored me and didnt answer.
