Both Studebakers were delivered today! Out of 9 tires, two hold air . I have posted a youtube video showing what I have found so far: https://www.youtube.com/watch?v=4dCN5XsSwUE
It looks like the Lark was better taken care of and will probably be the focus of the rebuild.
I am working on a list of things that need to be replaced/sourced, but first I want to see if I can get one or both engines turning. I have put some Transmission fluid in the cylinders to lube the rings before I try turning the crankshaft. I then spent the evening washing the thick layer of scum and dirt off the cars. They are much more attractive after a bit of cleaning.
