I was told that my underfloor ducts would be too small to handle the volume of air required by an AC unit. However, that has proved to be a non-issue. Choosing an appropriate AC unit is very important. Space was very tight, but the ducting has fitted in well. If you are thinking of making such a conversion, then hopefully my experiences will help you.

Broken head studs are common in Porsche 911 engines. This video shows how you can extract broken studs with only the tappet covers off. You can probably even do it with the engine still in your car.

H...
