Trying to find a specific gun mod for Minecraft 1.7.9/1.7.10?

I often play GTA style Minecraft on a Multiplayer server called cracked survival HC which is part of the Dragoncraft Network. In it, they have… I don't know, a mod or maybe even a resource pack that reskins all the tools as weapons. For example, the Golden Axe is a Desert Eagle and Purple Dye is now Pistol Ammo. There's also something that makes minecarts into red, drivable cars that work much in the same way horses do and you can drive them anywhere, even if there isn't a rail to guide them. The server asks you to download a resource pack upon joining so thats why i think its more than just a mod, but I can't for the life of me find out what it is. If anyone knows, please tell me!
