John, my "assembled vehicle" has been inspected annually from day one at the Plano DPS Waiver Office. Phone 972-422-5428 for an appointment. Or try your Dallas County equivalent. You must have your forms and your insurance card stating that you are a 1965 Ford Replica, or some words to that effect. And a postal money order for the fee ..
According to them, all of these replica cars with period emissions equipment should be coming to the waiver sites.
