Is there a special tool for putting this rivet on? My frames are back in, the lower pivot point seems rocks hard, you know it has those pins that stop it from rotating out too far, and they bend a little with use, and the bottom tab the lower mounting point slides into also gets bent with use, so I had mine straightened out, and had the frames powder coated. Got the rivets from VW for the upper pivot part, but someone said when they did theirs, it didn't look so good. Another person said to just use a ball bearing and a wrench. 

Any tips on this?
