Z28 belly pan

[_Onyx_Wolf_]

What bolts and nut insert sizes do I need to install to the subframe??

I installed the Z/28 Belly Pan on my 2013 1LE. It was not too bad but I will caution you that the underside of your front bumper cover will need to have about a 1" wide piece cut along the underside where the belly pan meets up with it. Otherwise your OEM bumper cover will go too far rearward and interfere with the belly pan.

Here are the part numbers you will need for the install:

(QTY) Part Number - Description
(9) 11610055 - Bolt,Hwash,M6x1x23 (Black with washer) (Z/28 Belly Pan)
(2) 11609982 - Bolt,M6X1X22,14.55 THD,24 OD,8.8, Z/28 Belly Pan (Silver with Large Washer)
(3) 11519385 - Bolt,M6X1X33,23.37 THD,17 OD,8.8, Z/28 Belly Pan (Silver with Small Washer)
(2) 22189414 - Retainer, Plastic, Push In Christmas Tree (Z/28 Belly Pan)
(11) 11570215 - Nut, F/CMPT AIR DFL M6X1 (FITS HOLE SIZE 9.5X14, 2-3.8MM PNL THK,PUSH IN TYPE, (Z/28 Belly Pan)
(1) 23459995 - Deflector, F/CMPT Air (Z/28 Belly Pan)

The quantities listed are minimum. I remove my belly pan everytime I change the engine oil so that I don't make a mess getting oil all over the belly pan. So the screws need to come out pretty often. I'd recommend ordering a few spares for the screws/bolts and the Nuts to keep on hand. The plastic Christmas tree retainer might get worn out too so I'd just order a few extras of those as well. But I like to be prepared.

I'm not sure if the nuts would work or not. They are designed for specific sized holes. You can see in the description of the Nut that I listed what the hole size dimensions are that the nut fits and the thickness of the material the hole is in.

You would have to see if the nut you ordered is designed for the same hole size as the nut I listed in my part number list for you.

Amazon will often have the GM part numbers so you could try searching the GM part numbers I listed and see if they are on amazon or not.
