I have a spare part in my toolbox, which I cleared out today. I seem to remember removing this from the rear of a scrap P6 fuseboard around 16 years ago. It is a plastic plate which appears to provide protection between the live terminals and the bulkhead. It has 2 holes for the fuseboard fixing screws to pass through and a horizontal raised piece suggesting a division between the terminals on the feed and supply sides of the board. My S2 V8 doesn't have one fitted - should it have one??
