overhead console has sharp clips on the bottom side, you'll need to measure where the console goes, then make holes in your fiberglass to attach to headliner board. again, don't have one in front of me but the front of the overhead console is pretty close to the front of the h/liner board, maybe an inch back.
first problem I see is that you still have the regular headliner bows installed. you'll need to get rid of them before attempting to install. .also, have ready the screws that attach the rear of the console to the center roof bracket, looks like its in place.
