Don't be afraid to get your hands dirty. Run the engine and listen for any unusual noises. Test the transmission by shifting through all the gears.

This is like creating a roadmap for your restoration journey. Be realistic about your skills, time, and budget. It is a long journey and it's best to be realistic about it. Also, it is best to consult with experts. If you're unsure about a specific task, don't hesitate to seek advice from a professional mechanic.
