You can get the rivets (that's what they are called) at any auto parts store. I got some at NAPA, part # BK 7702871

.

 

Cool, thanks for the part number too!

 

I have some that I get from Wurth. Here are their part numbers. You also will need a rivet gun to put them on. I have never tried a conventional rivet gun. This gun is made for these rivets.
The 5 mm goes on the back door flares. The rest of the Jeep takes the quarter inch.

Ok, thanks, appreciate that info!

 

I just bought these rivets from Clips and Fasteners Inc. I had to remove the inner fender to get to the antenna mount.

I have a pneumatic rivet gun and it worked grest with the plastic rivets.
