I love this idea and it will probably be the route I take in my all out 280 build. Sunny if you had access/the skill set/material to a full machine shop would you have engineered any of your parts differently? I ask because I work as a welder and have TIG/MIG/stick capabilities as well as multiple lathes and plasma torches. The car will also be flipped over on a rotisserie to shore up the frame rails and floor boards so I will have full access to the under side of the car inside a shop. Any lessons learned or suggestions that you care to share form this experience?
