In other words, unless you plan on doing this job a couple times (you should not need to), just bring it to a smith - cheaper than buying the tooling (870 Ejector spring rivet cutter and a REMINGTON 870 RIVET STAKING TOOL SET, Brownells has them).
I've done this job in the past. Not hard if you have the right tool and punches, BUT, the rivets will stand proud of the receiver when done and need to be filed flush. Normally doing an ejector replacement also requires the receiver to be refinished (re-blued) unless you don't care what it looks like. Then you can just slap some cold blue to it.
You will need a front and rear rivet (about $7 US each), the ejector (about $20 US) and the spring ($8 US). Then there is the labour...
D'oh, my bad. I have confused "extractor" with "ejector". Sorry, carry on.
