After buying 9 different packs of plastic rivets (clips) I found the perfect ones and thought I'd share.
Get them at McMaster Carr, part# 90218A222

pack of 100 for $7.69

They are a little hard to push in, but snap in the holes perfectly and hold tight.

 

Thanks for sharing. I was just thinking what I was going to do to replace the many that were destroyed taking my car apart.
