Ok, so I have spent 1000 on body kit parts to mix and match. as its winter it was taken off. Now I just think its all useless. Cause it just doesnt flow together. So I want to convert to full raven kit. So the front drift bumper has to go. I've been eyeing some duraflex front ravens but want to know:

Whats the best and safe way to secure a rear bumper? Cause I've drilled holes into the thing to secure the oem screws, but there was an incident in the summer and now I need to find another way to secure it without it looking ricy or something. Are there brackets or something I can get to totally secure them to the car? Thanks in advice.
