I just went through the ignition replacement today and using the same trick I learned from seat installation, it took me less than 10 minutes to reinstall the top screw on the ignition (yes the one up under the dash). Ok, so I started out with grand finale because while I did learn the super cool way to make this a super (relatively) easy job, it took me an hour and a half to figure out the trick on the front end. For those of you that have already removed/replaced your seats, you may have already guessed at the trick. For the rest, I'll pull a Tarantino move and start from the begining even though you already know the ending (or do you....).
I just needed to replace the igniton module, but I prepped to remove the whole unit if I needed to. Tip #1, get a 3/8" bit for your multi tool and cut a groove in the break-off bolts:
Next I drilled out the rivets and replaced the break-off bolts with stainless allen head bolts:
I didn't pull the whole unit, so I didn't remove the knee pad, but I was replacing my blinker and washer stalks, and noticed that with a stubby allen, you should be able to get to the retainer bolt:
