And yes, 6 people will give at least 6 different answers!

Yes I agree. Yours is the only 72 I've "seen" with original black plates. Every 71-older I've seen has had black plates. Factory stocks post explains the cross overs. If your truck still has the original plates issued 40-plus years ago then you just keep on renewing. If you are newly registering a truck with cleared OEM plates there is a lot of criteria to be met. I picked up a set of blue commercial plates at a yard sale, and when I called the DMV to see if they were cleared (out of the system) I was told they were, and also they could only be used on a 71-72 truck.
