X ray bulkheads eh, never broke any rears but loads of fronts. I contacted fibre-lyte and had some carbon fibre braces made and fitted onto the front. Never had a bulkhead break since and we run 3 cars at the same meeting.

They work out at around £6 each considerably cheaper than a new bulkhead. He should still have my drawing on file so it is easy for them to make them for you.
Might fit my spares on the rear now after seeing this.
