This is a recreation! I examined some of Pats old videos using the fury lucky block to add the drops. The original download on the forums was deleted and the dropbox link was made private so I figured I'd remake it.
To apply the lucky block, open up the original lucky block for 1.7.10 in forge and it should create a config folder in your .minecraft folder. From there open up the config, then open up the "lucky" folder and replace the original lucky block config for the new one. To change the texture of the lucky block, open the lucky block mod jar file with winrar and go the lucky block assets folder, find the textures and the blocks folder and replace the original texture for the new one. And boom! You've successfully downloaded this addon!
