I have an ERA FIA, right in your backyard - I'm in White Lake - about 30 miles West of you. Be happy to show you my car. Can't drive it over anytime soon - I've pulled the engine out to freshen it up. You are welcome to come by and take a closer look - and you can get a clear idea of the constuction with the interior and engine out of the car.
Send me an e-mail and let me know when you might want to come by.
regards,
Jeff
