Spitfire front spoiler installation

[Nolan Penney <npenney@erols.com>]

My 1980 1500 Spitfires front spoiler sags like a drooling child.  Problem 
with correctly mounting it is I can't figure out how it's done.  Two 
screws, one on each edge is all I see.  I do see a mysterious bit of 
rubber screwed into the cars sheet metal midawy across, but no matching 
holes screws or rubber pieces on the spoiler itself.  Just how does one 
prevent a drooler appearance correctly?
