What are the clips & screws I need to hold this up with? I just bought filler panels for underneath my camaro dash (covers up all wires, fuse box and passenger side). I Just want to know what screws, clips, etc i need to buy to install this. Plus a good site to buy new insulation for this as well.

 

I think you are talkin about the "hush panel".
It uses ordinary self tapping screws. Just place it in position and you will note the screw holes already in the panel. They should line up with existing holes in the bottom of the dash and other in place structure.
Insert new screws in the holes. Most are friction fit and don't require backing clips unless the existing holes are stripped out.

NO insulation needed..........My 84 hush panels didn't have any.

EASY fix!

Oh i got mine from thirdgenranch, and i got it for my camaro; they didnt come with screws; but what type of screws? the stock ones around other trim (example: under steering wheel column)
Plus mine had some foam on it.
