Well, that's making it sound easy!
After you remove the "top nut"(finial) you pretty much need to disassemble the entire antenna to do the repair.
The nylon cable inside that pushes the mast up and down is broke and the broken cable will be wound up inside the motor.

Check out this thread for repair process.............

I got my whole interior out right now (stress city) anything to do with an antenna sounds easy for me right now I would say just replace the antenna rather than taking apart a 30+ year old part , I do not recommend the Ecklers antenna I just bought one all it is is a universal antenna with a dozen parts you have to go through and figure out ... I would say look for a better replacement , I think the one I got cost $114 something like that.

The 78-EARLY79 antenna is a completely different unit than Late79-82. Used for only that 1 1/2 year period.
Same type of function and basically same repair.
I like to keep things original, and assume unless told otherwise that the Vette in question is hopefully low mile.
I agree the "correct replacement" antennas sold by the vendors is an inferior product.
