Replace the sound and the model of Crowbar TTT

Hello.

I have been trying to replace the model of the default Crowbar in TTT.

I want it to be this: http://www.garrysmod.org/downloads/?a=view&id=104388

People should spawn with this by default when they join the server.

I am trying to change the default lua file “shared.lua” from the crowbar which you can also find here: https://github.com/garrynewman/garrysmod/blob/master/garrysmod/gamemodes/terrortown/entities/weapons/weapon_zm_improvised/shared.lua

I dont want to change the damage, I dont want to change the animation, I just want the crowbar to look like the chrome baseball bat and sound like the bat. Model and sound files are included in the DL of the chrome basebal bat.

If anyone could help me do this I would apreciate it alot because I currently have no clue how to do it.

Thank you for reading!
