Hmmm…well.
Here is a different site: http://www.autobodyclips.com/
I recommend something like this:
Or
Rivet!!!
it needs to be removable and there is no access to the fastener. It has to be push installed…
autozone or advance has them,its the same on my honda.i slide them in my side skirt then push then into the underbody.its a pain
are the autozone ones car specific? or are they generic?
i would use double sided tape on the side, the on the botton use som self tapping sheed metal screws with a hex head. thats what im doing on my side skirts
