I'm at the point in my project where I want to buy the correct hubcaps for my '60 GMC, these are the 1959 model hub caps, (new 60-66 model year hubcaps did not roll out until 1961, GMC sorta overlooked these items eek ).

How do I go about measuring the size I need. I have the OEM 6 lug wheels but I'm unsure what/where I need to measure to make sure the hubs will fit before I order?
