I know it isn't original, but I just replace the rivets with little pan head screws, internal lock washers, and little hex nuts. Less chance of damaging anything putting them in, and you don't need special tools. Of course, someone really picky may notice it, but that's THEIR problem for being too anal about such things. It's how we did it back in the day, and it's good enough for me now.

That is what most people do - that is what I have done, especially if it is only one, say, a socket replacement on an average radio. BUT after you pay $400 or more to have a chassis re-chromed it is hard to settle for non-stock hardware. So keep that hammer warmed up - -
