I'm not sure who to believe. The OP shows a boiling point of 401*F but the pictures of the label on Autozone's website references a lower figure of 284*F.
The boiling point is important because spirited driving can 'boil' brake fluid, leading to compressible air in the system, and unreliable braking. Due to this mismatched information, I'm going to have to pass.

Regarding availability, my main store was out, but my second choice, about 4 miles away allowed me to buy 3.
DOT 3 and DOT 4 are often co-specified and interchangeable on most cars. The difference in the spec has to do with slightly different wet vs. dry boiling points. Both types are good for cars driven on the street. Better to change the fluid than to worry about precise details on the specs. Whatever fluid you put in there will start absorbing moisture from the atmosphere immediately, so change frequently and don't worry about brand or exact quantitative ratings. Just my opinion, which is 100% correct.
Great deal.

Now class, let's review- I said:
"I don't know of any current production vehicles but there have been plenty of production vehicles specifying DOT 5."
Now stop being annoyed and go back and like my post. Then go sit in the corner and think about what you've done.
I stand by what I said.
Don't worry guys. Old fluid will mix with the fresh and won't ruin the new fluid you just put in. Life will be ok! No one is going to lose their brakes and die in a fiery crash!

Depending on the wheels, you might be able to reach through the spokes, or around the side (maybe turning the steering to one side or the other to help), eliminating some need for jacking and wheel removal. Be aware though, that some calipers have bleed screws on both the inner and outer sides.
And if you really have no tools and don't want to risk messing things up, a still-helpful and very easy thing to do is:
- Get a turkey baster (or equivalent), donated from your kitchen drawer or bought from the dollar store.
- Suction out all the fluid in the brake fluid reservoir.
- Refill with the clean new fluid.
Definitely not as good as a real flush, but definitely helps and almost impossible to make anything worse. The brake fluid will circulate throughout your system when driving, and the clear new fluid will eventually become darker, but not as dark as when you started.And if you find yourself with an opened partial bottle leftover from working on some of your cars and don't want to put it on the shelf, you can use it to do this reservoir fluid swap on another of your cars.
