Hey guys...I'm installing a new windshield washer resevoir on my KJ this weekend after mine had a crack in it...dont know how it happened

. Anyways...I'm going to attempt to install it myself. I found this tech article to help me:

My question is...do you need any special tools to reinstall the plastic rivets? How many will I need to put the front bumper back on? And to save myself the embarrassment at the parts counter....is that part number for the rivets found at NAPA or do I have to order them through the dealer? The number is: NAPA part# 770-2871 correct?
The first part of the part number is napa...so I'm just making sure! Thanks in advance guys.
