question about removing a arm shaft nuts

[swierker]

Sorry if this is a simple question but this is my first time with a front suspension rebuild. What is the best way to remove the A arm shaft nuts (the ones at the ends)? The lowers look like they need over a 1 1/2" wench or socket to remove them and I don't have anything quite that big.

Is there tool from one of the auto parts store for loan that can be used for this? Or do I need to find a wrench or socket that big?

The A arms are from my 70 C10 and they have been removed from the truck.

Thanks in advance.
