How do I replace lower door hinge arm rivet on a 3rd gen Nova???

[scherp69]

I'm going to be ordering all the parts to rebuild a set of stock hinges. I also want to replace the lower hinge arms, but I'm not sure how to reinstall the arm rivets. Here's the part I'm talking about: http://www.classicindustries.com/nova/parts/hc241a.html I can't use a press since I'm using 73-74 doors and will be using half of hinges which are welded to the door. The arm is on the part of the hinge that is welded to the door. Is there some type of tool that I can use? After doing some reading, these same rivets are used on first gen Camaros.
