Replacement PDP accessories?

Hello,

We seem to have lost the nuts/cover/tiny bolts that secure the battery leads for one of our PDPs. Is there any way we could buy replacement parts?

It’s labeled as M6, so we should be able to secure battery leads. But what about the plastic cover? Would covering it with some electrical tape be sufficiently safe?

(We’re also missing a 20A fuse, but we have a replacement for that.)

Thanks, I had only checked AndyMark.
