I'm stoked! While messing about in the middle of nowhere, I stopped in an antique store and found an Indiana 1967 plate. Some rust, but no dents or folds. I gonna restored it get it registered.
While on the topic.. I found some mint condition 1968 warranty packets. All the stubs are intact. Let me know if there is any interest. If there is, they have hundreds of plates from all over the country. If you need one, sent me the state and year and I'll see if I can find one.
Oh.. the best part.. The license plate was $5.
