I would give it some time before I started to part it out! What if you end up keeping it...would be nice to have the little things like the Ring hinges.
I know you wanted to build the car yourself, but since you have a friend that can help you may go that route. That way you at least get your dream car in the end.
I set out to build my car entirely on my own other than paint.....things change and that's ok.
Just my thoughts..................
