use a block of wood. or, like in my case if a block of wood is not available, you could use coins.
Ibanez Xiphos XPT750
ESP Ltd Viper 400
Egnater Rebel 30 112
Boss GE-7
Line 6 Uber Metal
Boss DD-7
just fill the void where the trem floats....btw when blocking metal produces better tone then wood blocks
Whatever you do, wrap the wood or metal i black electrical tape. This this will make it so the object doesn't chip or scratch the finish off your guitar.
Use a tremol-no there pricy at £54. check the website for which one u need i think its a pin type for edge III
