Old style crager wheels and tires fir my duster. Opinion needed

What's the manufacturer's date on those L60 tires ? I would think they're old as they haven't used the letter designation for quite some time if my memory serves me. The rally wheels should be fine.
I'm not sure what the year is on those tires.The ones still have the paper on the tread. The rams are new as well He said when he test Mounted them on the back of his duster.The tires hit the springs a little..... How much are those rams worth 15x8 bbp
