Samuel,
I have been using a California car cover for years. The cover fits very well but you will have to make a hole for the antenna. The instructions that come with the cover explain the proper way to make the hole if I remember correctly.
By the way 1981's had all three variations of antenna location (in the windshield, the right front fender and left rear retractable). This is probably why they did not automatically put a hole in for the antenna.
