Auto Parts: Retaining clip on rear wheel cylinder, wheel cylinder, retaining clip

Question
How do you install a rear wheel cylinder retaining clip on an 89 S10? Any tips?

Answer
    It's pretty simple, actually.  You brace one hand against the wheel cylinder from the outside and drive the clip home with a large socket or piece of pipe.  Of course, you have to do this before you attach the brake line or the pins for the shoes.  There isn't much resistance to the clip going on; geometry makes it tighter as you try to remove it, so it won't come loose.
