My front valance was somehow ripped off the bumper cover, I assume from a parking block. My question - to reattach it, is there a way to take it off and then slide it in and re-secure it, or do I need to take the entire bumper cover off first, attach the valance, and then re-attach the combined unit.. Sorry if that question makes no sense, I can't tell from looking what order these pieces are assembled. (Please disregard ugly zip tie attempt to keep it together, I had to field dress it while away from my garage)
