I guess I was lucky. I used a piece of sandpaper to grip the socket and was able to loosen the nut.

The inner wire:
The cable tends to rust-up when not used for a long time. I've been lucky sometimes to get one working by wiping the housing with a rag to get off the grime and a little rust. Then put penetrating oil on a rag and run it along the length of the cable. Flexing the cable helps to get the penetrant inside. Repeat the process. The knob is crimped on the inner wire. If you can get all the old inner wire out, it's possible to take a new inner wire and knob (may have to buy a complete cable) and run it through the old housing. The end of the inner wire needs to be rounded to keep it from snagging. You can also spin the knob as you insert to assist the inner wire to move.

Radio grille removal:
It is much easier to access the throttle cable nut with this grille removed. For me with stubby fingers, it was harder to get the lock washers and nuts back on the grille. Place a sheet are something on the floor to catch the nuts/washers that fall. Have extra nuts and washers handy. Make sure nothing falls down on the ignition switch (may be safer to disconnect the battery first).

While you are down there with your body contorted and feet in the air, you may want to lubricate the cowl vent mechanism, replace all the dash lamps, replace the old defroster hose, replace the glovebox liner, and anything else that may need attention in the future.
