 These, when bent outward just a little, fit into slots on the far side of the steel bushing pressed into cam cover. \\
 Here's how the factory assembled this thing. \\
 They had pre-assembled the brass to the steel before the steel was pressed into the cover. \\
 Then dropped the spring into the cover and pressed the brass/steel assembly into the cover as a unit (and manipulated the spring to sit correctly if needed). \\
