Hooray! Replaced both plastic clips on the DS front yesterday. All is well and working now! Guess that really is all it was. Local parts store ordered for me and sold to me for $1.25 each. Wish I had some way of knowing exactly how much to tighten the bolts, though. Don't know whether to leave them looser and take a chance on them falling out, or tighten down hard and bust up those plastic clips again.

Seems fine for now, though!
