Deck Logs for LST Class Landing Ships, WWII

Seeking information for my grandfather, SM3c Delbert Earl Scudder.  He served as a signalman during the Invasion of Normandy on LST Class Landing Ships and he was discharged on April 5, 1946 although the date is barely legible on his documents.  I believe that he served on LST-529, USS Cayuga County, and possibly on a couple different ships during his enlistment.  Any information would be greatly appreciated!
