in my assembly manual it says to use cement #9985027 on the fillers! Is there anything else that I can use to install fillers onto my bumpers? will 3M contact cement work?

 

The front ones have 3 rubber tabs that mount into the 3 holes in the bumper, these usually stay right there. The rears slide into place and again usually stay put, if you want fast acting stuff you car use crazy glue or that adhesive works also.

 

I used black weather strip adhesive on mine. Put light coating on the rubber and a light coating on the bumper points of contact. Waited a few minutes and attached. They've been in the same place for over 10 years.
