1988 90q front turn signal assembly question

["Smith, Kirby A" <kirby.a.smith@lmco.com>]

Sometiime Saturday night my driver's side front turn signal assembly fell
off the car.  I got a new one today and installed it, and tied it in with
floral twist tie wire for safety.  Good thing.  It was loose when I got to
work.  There doesn't seem to be any good grabbing going on between it and
the fender and the headlight.  On the fender side are two springy plastic
parts; on the headlight side are essentially four locatiing prongs, two of
which have bumps on the end that are tapered in a way that they don't lock
in place.  (As distinguished from, say, the way the right headlamp rear
shroud that locates the air duct locks in place.)   Am I possibly missing
some metal retainers that fit in the headlight assembly and hold the turn
signal assembly prongs more firmly?
