Trevor,It's much easier to keep focused on the end goal if you have some kind of GT40 stareing at you everytime you walk into the garage. My Tornado might not be perfect but hey I am living the dream, I own a GT40
It seems with your circumstances you've answered your own question. We all have different priorities and resources in life. I would not be ashamed to have a GT40 kit that isn't as original as someone else's. Be thankful that you have a GT40 replica period. Most people won't know the differences between replicas. Push ahead with your Tornado build so you can enjoy it before you are too old. Driving it will be as much fun as the build.
