Antenna Question
On my 1979 Corvette there is a gray plastic part which is connected to the second section of the antenna. Does anyone know how that is removed from the antenna, or if it even can be removed. There is a part of the mast which broke off and is stuck in that area. I should be able to reach it if that can be removed.

That gray thing is a CB load coil.
It unscrews. Take a couple flat pieces of wood about 2" long and clamp them together. Drill a hole slightly smaller than the mast section the gray thing is attached to lengthwise through the seam of the two pieces of wood.
Then clamp the blocks to the mast just below the gray thing.
Wrap some tape around the gray thing and use a pliers while holding the wood blocks with another pliers.
If the mast section turns inside the wood block clamp you drilled the hole too big.
BUT, removing the gray thing won't get you anywhere repairing the antenna. Repairs to the mast need to be done through the botton after removing the motor.

Sounds like you have a broken nylon cable inside?
Do you have a late79 antenna(plastic body motor) or an early 79 antenna(aluminum body motor)?
The aluminum motor is easy to get to a broken nylon cable inside, with the mast assembly removed from the motor just insert two small screwdrivers into the mounting holes and pry out the plug.
The plastic housing motor antenna is similar, but you need to pry the metal away from the plastic plug at the base of the mast.
I've successfully worked the broken nylon cable out the little hole at the bottom of the plastic motor mast by turning the mast section while watching in the hole for a glimpse of the broken cable and then catching it with a micro screwdriver.
Also, new replacement nylon cables tend to bind at the nylon/mast connection. You may need to fine tune the metal connection perfectly round with a hammer.
