How do i change the Vic's Gangmembers Weapon?

[keyan]

 

Hi guys GTA VCS is one of my favourate game from my chieldhood till now. 

i saw this video on youtube. 

This is soo cool. Would be cool if anyone here tell me how to do the edit  Vic's gang member weapons like in the video. I even asked the video uploader and he's not responding.  I also use the Mod menu that has a custom script can spawn a bodygaurd and i can edit the file easily to change the guns. Hope somebody still plays this awesome game

have a ncie day.
