Dave, the top right corner of all posts on the forum have an area with cobra make listed. You can choose most anyone to send a private e-mail with questions via this forum. Cobra owners are happy to talk about their labor of love. FFR (Factory Five Racing) are numerous. ERA are harder to find but, I can think of 2 right off the bat. Robert McLindin in Chandler and Dennis May in Scottsdale also known as Snakebitekit.
If you can attend most any gathering you'll find lots of answers.
