F18 GEAR BOX FOR A VAUXHALL !

here I have a F18 GEARBOX that i do know is for a vauxhall but which one i do not know, i brought this a few years back from a gearbox place in Birmingham but can not remember there name of the place but it didnt fit my car and they wouldnt give me back my money, was a dodgy place i would say should have done some research before i paid for it. but have notice,well heard when i came to move it from the shed i heard like ball bearing knocking around so i would say spares and repairs has i do not want to get people hopes up and say its in perfect order when clearly some things lose inside
