I assume you are talking about a 52 Chevy Pickup. The normal adjustment to straighten a steering wheel is in the drag link. However, your Chevy Truck has a solid drag link with no adjustment.
Pull the steering wheel and put it back on straight...
You will need to remove the horn button , then the nut that holds the wheel. A steering wheel puller will most likely be needed to release the wheel. They are available to rent or can be purchased in the $ 25 dollar range..
