The nameplate on the Indian with the cast aluminum gas tank is pinned on with very short drive pins. The holes do not penetrate the inside of the gas tank. If you find a replacement nameplate, whether it be original or reproduction, you will have to remove the broken ends of the drive pins before mounting the new plate. Otherwise, you can use a good adhesive and glue drive pin heads over the ones that are broken off. The original drive pins were not that hard, so you may be able to get them out with a pick or possibly carefully drill them out, but do not penetrate the back of the gas tank.
