Here are the finned valve covers and new gaskets finally installed! And none too soon either. The old gaskets fell apart in my hand when they were removed.
Here is the necessary repair to a stripped door mounting bolt. When the bolt bracket in the door stripped, I went to the hardware store, bought a longer bolt of the same thread type, and a lock nut. I then stuck my arm into the door and installed the nut on the other side of new bolt. A success!
