How to transfer 3D accessory (goggles) and match texture size?

[connseanery]

I'm trying to transfer goggles from one player (Jalen Smith) to another. I've gotten to the point where the goggle model looks ok on the new player but when I copy the textures over from face8005_goggles_04_geo.iff to the player png, the size of the goggle texture doesn't match the goggle model.

Please see example

Would someone know how to properly match the texture size to goggle model?
Thank you
