Well done!I have done mine and a few dozen more on my custoners cars and I always need the rivet gun and an assistant to hold the fenders in place while I use the rivet gun to ensure the rivets are pushed in properly.
That little stick in the rivet is pushed in so that the rivet opens up!To take the oem rivets out you need to push them in all the way until they fall out!To put the new ones in ,you have to rivet them in(they are very hard!You cant even hammer them!) until they are flat level with the rivet surface...Cant figure out how you push them in without a rivet gun????Also what do you mean"..use a nose plier to pull out that little stick"???There is nothing to pull out,only the rivets themselves,and only after you push the stick out!!!
Even if you did manage to pull the little stick out with the nose pliers in removing the oem rivets,(much easier to just punch them in!)how on earth can you push the new ones in without a rivet gun???
