[1.7.10] change ore harvest level

industrialcraft-2-2.2.828-experimental.jar
I want to make copper harvestable by level 0 (flint) pickaxe for I disabled wooden and stone tools and then added copper ones as stone level.
Can i change it in mod(i havent found where copper ore block is only ic2/core/init seem to do something wih it) or what tools should i use to alter ore's level(aditional mods for example)? Moving flint tools to stone level - not an option.

Ok. I've been for 3 whole days searching all the internet for solution and trying whatever i could think of... And it was somehow solved as soon as i posted here! For ones who want to do the same BlockProperties-1.7.10-0.1.5.jar was what i found. Still if there is more variants I'd like to know about them. This mod seem way overkill for my needs. Sorry for my english(not native) and have a nice day whoever reads this.
