I've got the early black vinyl seats as seen here

Based on previous advice i felt around the top and there does seem to be some holes under the vinyl where the headrrst would go. How easy is it to fit and what would I need? Headrest wise i'd try to source some of the simple, early vinyl ones a bit mike these on ebay of the come in black too
