Need to replace both window regulators

[sokoloff]

So today both rear windows of my '99 E300D gave up the ghost and fell down into the door. I bet I have replaced those regulators half a dozen times in the twenty years I've owned the car. It's been awhile though, so I'm asking for any updates from those who have done it recently. I have notes that I have replaced the rivets with bolts, lock washers and nuts, so I won't have to drill out or reinstall rivets. See attached photo of parts I happen to have in stock. I think the only part(s) I may need are the door trim clips in case any of them break. So please give me any advice you have and tell me if the only parts I need are the actual regulators for both sides. I have seen and will pay close attention to the "how do" articles here.
Thanks.
