I've owned a base model '79, '80,'81. All had manual steering, windows, 5 sp and R180 diffs. I've owned an 82 and 83 slick top, the 82 was a base model, but still had A/C. Although it was not the auto climate control. The base 82/83's exsist, but they are even more rare than the 79,80,81 years. Probably as rare as the '81 turbo slick top.
