My '65 Galaxie is fine in the wind but...the problem I had with my 1963 Impala was the same as Dave is experiencing...with all 4 windows down on the 2 door hardtop Impala it was exactly as said...like a parachute deploying...once the back windows were rolled up the problem went away.Marla[img]/forums/images/smiles/icon_bicker.gif[/img][img]/forums/images/smiles/icon_cry.gif[/img]
