Having difficulty installing rubber bump stops in upper control arm for a 1970 Camaro. It seems impossible to get the tab connected to the rubber bumper, through the slot of the control arm, without tearing the tab. I've used silicone grease to facilitate this, but it becomes so slippery, that the pliers slip off of the tab when any force is applied or I just rip the tab from the stretching needed to do this. The upper control arms are not connected to the spindles yet so I can rotate them upward to access the bottom side, but that doesn't seem like it will help push the tab through the slot. Help!!!!!
