Bill,
The Earl's I was referring to is Earl's plumbing, typically known for their race car plumbing. With some measurements, I can get the appropriate suspension hardware and such from them. AED Motorsports would supply my chromoly, along with other local suppliers that cater to the motorsports industry in Indianapolis.
I appreciate all of the in depth responses. Hersh, I most certainly don't want to get caught spending years doing my first Cobra build. What got me interested were past reviews of the on the track performance. I don't want something that just looks good. My goal is to spend 1-2 years to build one, a realistic budget, and it would be helpful to have contact with former owner/builders when I have questions.
I'm still trying to look at pictures of similar fiberglass bodies cars to see exactly what all needs to be fabricated. If I decide to go further, I'll PM you Bob.
