I picked a random Lendl match and found an impressive amount of amazing passes, especially frequent in the third set.
I even watched the whole match for you,
NatF, and noted timestamps for the passing shots
AND THEN MY COMPUTER CRASHED.
...
I've just searched again and fortunately Krosero actually compiled a short highlights of the very full match I found which contains most of the shots I listed in notepad.

I'll post the full match anyway:

Go to 26:55 for a nice slowmo replay of the first pass from the highlights video.
There is a portion in the full match where the commentators (which includes Rod Laver) talked about how Becker seemed to be avoiding coming to the net out of fear for Lendl's passing shots. By set 3, I noticed that Becker just felt he had to attack more, and he got duly punished... so now also imagine a Nadal or Federer, as they would provide a similar fear.
Lendl was capable of going anywhere and everywhere with his backhand pass and his forehand was brutal in all situations.
