Next time I'm at my storage unit I will see if I have any mk3 wiper switches. If so its yours for the cost of shipping.
I would guess the total time for replacing the stalk is 15-20 minutes.
Yank the air bag...5mm allen wrench
pull the steering wheel....24mm socket
pull off the steering column trim (not certain may a couple screws and you may have to pull the knee bar cover)
Then its just 3 screws for the switch and a plug.
Being in my ultra busy season at work I can understand not having 20 minutes but the 20 minutes is probably also required for the fuse/switch trick.
Just yank the fuse until you get time to repair it correctly
