Bumper hardware

I replaced my front bumper cover due to being hit. The original did not have anything holding it on in the lower opening. There are 6 holes that line up with the inner bumper. Does anyone know what hardware is supposed to be here? I would think push pin type fasteners but not sure. Thanks.

Well, I just went to gmpartsgiant.com and was able to see this picture:

It looks like they are RETAINER,FRT BPR FASCIA CTR SUPT(BLACK)(6.3MM DIA X 23MM)(1.276) Replaced by: **589290

You can search the site and verify.

Yeah, they were probably plastic push pins, like #'s 11, 13,16, 17, 18...

I think what you need is a picture of the inner fenderwells/splash shields.....they attach to the front bumper, and should show the fastener....

You didn't specify the year and model type....like LS, GT, GXP, etc.

I just bought a package of ten of the ones labeled #17 in the above link at AutoZone for about $6.
