I saw another thread posted last year but never saw an end result.
ive got an 06 monte ss and the front end seems to be sagging a bit...
ive tried replacing the the plastic pop locks and even inserting foam washers to lifter up a bit but still no bueno.

any advice on how to fix it up.
trying to do before I paint it.

 

Do you have a picture you could post? Your description is kind of vague so I'm not exactly sure where the front bumper is sagging and the severity of it.
