Check out Kat's. They sell several different types of oil and block heaters, including a magnetic one that you just pop onto your oil pan. I've read about people using them on air-cooled cars with good results. Kudos to you for driving a Ghia through the winter!
Edit: They also have glue-on pads like this, which are basically the same type of heaters we use on the aircraft engines I build.
They make oil block heaters that are big stickers that attach to the oil pan with a plug that you can run out the front of the vehicle so you can plug it in. A friend of mine did that with his and had no issues. He may have attached an additional one to his transmission pan as well. I would suggest looking on Amazon, but it may be better to look locally with Amazon shipping being what it is to Alaska. Here is an example for what I was talking about, it looks like they have some that screw into the block somewhere so that may be an option as well.
My old-battery car takes some finger-crossing to start at -10, and is practically un-startable at -20... unless I have had my oil pan heater on for about 2 to 4 hours. Otherwise, the oil's just too thick to let the engine turn over effectively.
