Records from the 76th Division?

[Guest]

I'm trying to trace the footsteps of two relatives who served in the AEF. 
They entered service in April 1918 and were enlisted in company A and L of the 302nd infantry regiment, 76th Division. They arrived in France in July of 1918, and I have no other record of their movement until one of my great uncles appears in the regimental history of the 305th regiment (joined company A, October 22nd 1918.)
I have a cryptic reference from a 76th Division webpage that "the 76th Division, minus the 302nd regiment, became the depot division."
Does anyone know where I could find records of the operations of co A and L, 302nd Inf, 76th US?
