Have a google search for that model car.  But a lot of GM cars of the era used the same setup. There is usually a lock ring nut that needs to be removed. It has 2 slots 180 degrees apart that are used to remove it. Now there are special tools for this but you can use a screwdriver or 2 by putting the bladed end(s)in the slot(s) and applying pressure counterclockwise to rotate the ring out but there is the danger of damaging paint by the screwdriver slipping and also the danger of damaging the slots of the ring. Recommend special tool. After that there is also a small latch or tang that holds the wiper arm onto the pivot spline shaft. You need to push out the tang before the wiper arm will pull off from the splined shaft. I have always used a small bladed screwdriver to release the latch or tang. If you have a small mirror that you could use then I would suggest using that to look and identify where exactly the tang is.

This tool for most 60s GM cars. These are the arms that slip onto knurled pivot posts and have a tang that appears to grab the pivot post, but in fact does not even need to be touched to remove the arm with a tool like this:

The best part of this tool is NO PRYING on the car, so no paint chips!👍

 

this is just one example, there are similar tools sold by most tool manufacturers. Just several pages down in Google since arms held on by nuts are so common these days, and those pullers are on the first few Google pages when you type "windshield wiper removal tool"
