Penney raids Quakers for staff
Gray was Penney's right-hand man at former club Darlington and the pair worked together to help the Quakers reach the 2007/08 League Two play-offs.
Andy Collett has also followed from Darlington and has been appointed full-time goalkeeping coach at Boundary Park, replacing Mark Crossley.
The new backroom duo will work with existing coach Lee Duxbury, who remains reserve-team manager.
