I am preparing to retro-bright one of my old IIC's that was pretty yellow. I have it completely disassembled but ran into one snag. The upper rubber keyboard gasket was so dry and brittle it was just fragments of crumbly rubber. Any chance of finding that part anywhere for sale...came up empty on an Ebay search? If not I figure I could make my own using the lower gasket as a template. The lower keyboard gasket was still in good shape....surprised it wasn't in the same shape as the other.
