I have an extra valve cover I could sell if you don't find one elsewhere. I live in California (near SF) so depending on where you are shipping could be expensive.

My opinion would be to try to revive it if the car is not rusty or doesn't have any major mechanical failures that the parts can't be found to fix. People are often quick to give up on them but there are few enough left that I think the ones without rust or major accident damage are worth at least trying to keep on the road.
