Very sorry for your loss, that's a difficult time only made better by time. Pulling the steering wheel is quite simple, only caution I would give is once you have the big retaining nut loose, leave it on by a few threads. You will need to "pop" up the steering wheel by hitting it from below with your hands. The nut keeps it from flying off. My wheel was off center when I got the truck, previous owner had everything apart, and it was easy to re center the wheel once it was off. As for delayed wiper, I'm envious. I missed an opportunity to pick up an assembly with delay a few years ago and have never come across another. With the light rain we have so frequently, I would love to find one. Be careful with yours! If anyone ever comes across one, I'd be more than interested.
