You'll fret about it longer than it will take! All in all, I'd say less than an hour, including R/R of the radio.
I used an oscillating tool to cut the flap and a decent quality duct tape to cover the flaps. The tape takes a little playing with to get it in place. I cut multiple pieces for each flap. There may be a better choice for covering material but doing any of them will be a huge improvement in heater performance.
I also used the same duct tape to reseal the flap I'd initially cut. I done this procedure in a 986 and 996 and appreciate the original post that let us all in on the secret!
Disclaimer: I live in NW FL...our winters are mild, yet we do need heat in our cars off and on for a few months. I can't say for sure the heater is effective as it was when new, or repaired by other methods. I can say it sure is good enough for temperatures down to freezing.
