I doubt there were many uniform issues in June of 1864. The ANV was pretty busy fighting every day in Grant's Overland campaign. If they did receive an issue they would have gotten whatever the Richmond Depot had on hand at the time. You can find uniform information in http://www.military-historians.org/company/journal/confederate/confederate-2.htm
Some pictures of dead Confederate Soldiers can be seen on the Lib of Congress site which were taken in May/June 1864. Shows them in RDII jackets with eagle buttons.
