Was changing rear end oil in 78 camaro & the c-clip retainer bolt was broke .So changed out pin & retainer and seems like a bit of play in carrier holes. this rear end is a posi unit & damn fine one so if there's some way to help keep the C-clip pin in place iwant to try it. Can't afford C-clip eliminator rear ends so i'm looking 4 insurrence . Ideas ? later bake
