69 Dart side markers

I have a quick question hopefully someone can help me out with.. How did they hold the side markers in the quarters on the 69 Dart?? The fronts have a bracket, long studs and nuts.. the rears however I cant figure out.. there is no where near enough room between the quarter and the trunk floor extension to allow this set up.. plus the new quarter I hung from Stephens Performance seems to have a 'bracket' already part of the quarter.. so.. were there clips used or what? I am somewhat lost on this one LOL ...
