Chris: Were you able to get the bumper aluminum deco ends to lay flat against the FG bumper? In past builds, I've used a block of wood and a C' clamp to draw the aluminum down, occasionally a small gap would remain. My fix, a self-tap 5/15" hex head screws every 2" ( do a small pilot hole ) it draws down and the heads are hidden by the rubber deco strip. I used a cut off wheel to remove the screws extending through the back side of the bumper.
