i don't understand why you need those things - you already know and have admitted that you did it, so why do you need proof? you also know there were signs saying that the car park operated 24 hours a day. They clearly have proof it was you, otherwise they would not have been able to chase you to court. Therefore it follows that they have both of the things you have requested, despite no producing them yet. What is the basis of your defence going to be?
