Replacing the heater fan in a '91 Volvo 240.

The way I understand it, the AC blower, motor and ducting are held firmly in a jig in Trollhatten, then the rest of the car is screwed to it as it progresses down the line.

Getting that thing out is a challenge far and away more strenuous than you would think.

Surprisingly easy: water pump on a 1980 Chevy Citation. It's its own little housing just hanging down there. Couple of bolts, hose clamp, Bob's your uncle. After replacing about five of them, Dad could do one in about 30 minutes, that includes throwing down a doormat to lay on. Then he bought a genuine GM replacement pump and never did it again.
