Erick,
I do not have any thing on them, but they are listsed with the National Archives. The following numbers represent microfilm Box, Roll and Number wjere they can be found: Robert Bush, Co. B, 8 Al. Inf. pvt. 000374, 0007, 00001566 and R. T. (not under Robert)Bush, Co. B, 8 Al. Inf. Pvt. 000374, 0007, 00001598. Therse numbers are not neecssary, but they may speed up your search, if you visit the National Archives or one of their regional offices. If you are in Atlanta go by and look them up their compiled service records. You can order thers records but it may take a few weeks to get a response.
Good luck
Wayne Adams
