soldiers at wrexham barracks germany at 1979

Hello everyone, I am from Germany and this forum is my last chance to help my aunt searching for her boyhood friend Peter P. or Pete P. who was stationed at Wrexham Barracks in Mülheim an der Ruhr in Germany in the late 70s early 80s.I do not think that it is allowed to write the whole name. He had blond hair and blue eyes.His buddies names were Tucker, Terry, Alan... They often met in a pub called Fuchsbau or at the river Ruhr.My aunts name is Jutta and her friend's name was Petra.Jutta was 17 in 1979. Can anybody help and still has contact to Peter.If so please help and write. I could send pics as personal message.Thanks everybody. Kind regards Isa
