Here is a build converting an Anovos to ESB full of helpful info
Looking at the thread apparently trooperbay sell Anovos specific ESB decals so you could contact him to confirm
A lot of AM kits come with ESB clamshell handguards which many don't use, may be worth putting up a wanted add in the sales sections.
You can use rubber gloves or silk/material. Gloves must be either black silk, satin, or silk-like material, or gloves must be rubber or rubber-like chemical gloves, in black
I found fabric gloves at a local store.
