Hey Tony,
When you purchase the rear tonneau area - where the flip up battery cover is - you usually get the correct color vinyl with that interior kit that is glued over the interior wheel arches. Rest should be armacord, not carpet as many cars seem to have. I have purchased that exact kit from AH Spares and their quality is excellent. Also, the boot armacord should match the rear tonneau area if my memory serves me right. You can also go to John Skinner in UK as they also sell the correct interior bits. Believe Moss only sells black boot kits, not sure about rear shelf kits.
Regards,
Mike
