I Need a couple world models put on the hl2 bones.

Hi, I need 5 world models put on the hl2 bones. I’m making a swep pack of PVKII sweps and if anyone remembers my last swep pack people didn’t like them mainly because they were crotch guns. I have tried to use the hl2 decompiler and i can’t figure it out so if anyone might wanna help I have models i need fixed uploaded on filefront. If this is the wrong section I’m sorry. http://www.filefront.com/14769391/models-that-i-need-put-on-hl2-bones.zip/

Could someone at least give me a tutorial for fixing the world models?
