I have been googling for hours trying to find a picture or specs on the types of clips to no avail. If anybody has the specific size or style or name of the clips or retainers that are used on the built-in bolts that stick out of the front bumper cover of a 1989 Firebird Formula, I would greatly appreciate it.

 

Solved: the rivetted studs that are affixed to the bumper cover are not designed to have any nuts that mate to them. The bumper cover is held to the fenders by two (2) u-clips and bolts and those 4 (four) rivetted studs only serve as guides when putting the bumper cover back on the car.
Also, on the bottom there are seven (7) plastic push-in clips that affux the bottom of the bumper cover to the bumper.

Thanks to TallTim for selling an awesome 1800+ page original field service manual in searchable pdf form. https://www.thirdgen.org/forums/member.php?u=115343

 

cool do you have a link on where to get the manual?

 

Follow the link in my previous comment and it will take you to TallTim. Send him a message inquiring on a 1989 Firebird field service manual pdf and he will e-mail it to you for a paypal payment of $40.
Before you scoff at the price, it's an 1800+ page searchable pdf format that he scanned in by hand over several months, and it's divided into easy-to-read sections. He'll send you a sample too before you purchase it so you have an idea of what it looks like.
I gotta say it's one of the best purchases i have made for my Firebird.
