Help with mod

[darkwolf176]

Basically I want to change the mesh of the eyeglasses, to make them less feminine.

I've extracted the two meshes using FO3 Archive:

glassesblackrimmed.nif

glassesblackrimmedgo.nif.

 

Which one do I import into 3ds max?

 

Also any links to max tutorials would be really helpful.

 

Thanks
