Got a few SLC racks onsite that all the plastic end plates in them are going extremely brittle due to heat and Oil exposure. I just finished replacing one where the end that is supposed to support the power supply via the retaining screws i can just about crumble up in my hand.

I had a bit of a search around and i can't see any part numbers specifically for the plastic bits, has anyone else had any sucess in obtaining them without having to replace the whole rack? We use all the different size racks throughout the site but it doesn't really matter as the parts are interchangeable between them anyway.
