OK guys I need your help, no shop manual for this one. I picked up a mid 70's Lincoln rearend already out of the vehicle with the disc brake set up. Trying to get the caliper off. Here is a picture of the clip, I am guessing the whole piece slides left or right (if it were on the vehicle) and comes out so that the caliper can be removed off of the rotor. Any ideas here? Before I beat the crap out of the clip like a red headed step child? There appears to be a spring clip against the caliper and the "wedge or slide" clip, which in turn slides over the lower bracket. Any and all feedback appreciated.
