Be careful bending them, they can break.They get bent in as the pads wear, you need to bend them out before pin installation.
Ya, Ma Mopar did away with using them, in later years, on cars still using the pin type calipers.Someone please educate me on what those things do exactly. The only thing I can see is that they hold in the rubber bushings that fit into the caliper. All the reman calipers that I have used have a shoulder on both sides of the bushings to hold them in, so I have left them off. I think they did away with those things in later years.
