I just recently took the wing off my 98GT. Autozone, or any auto parts store sells these little plastic "body panel" plugs; They are catagorized in actual manufacturers, i.e. Ford, GM, Chrystler etc..I bought some of those; They didnt quite snap right into place, so i used some silicone sealent on the parts that would be touching my deck lid..Worked like a charm, and i can always take 'em off if i want..The silicone just peals right off.
