Molded Headrest info

Can you make a mold and make your own? Seems nobody makes them for a A-Body.

I have one really good one and one with a couple minor splits. They look like it would be very hard to make with new vinyl.

This is off a 67 Cuda.

Also thinking of trying to glue the seams that split with some sort of vinyl cement and dying them, just dont want to make a mess of it and have it split again.

What can be done?
