Need to title a title-less car with no history- HELP!

So, I have spent the last 4 years of my life completely restoring my fathers 1967 barracuda. Painted it vit. C orange, put a bored out 340, threw a 4 speed and hurst shifter in it :burnout: ... so when it came time to put it on the road my father was ready to sign the title over to me on my 18th birthday he finds out it was in HIS fathers barn which burned down along with the rest of the information on the car. Bear in mind that this car has sat in this front yard for the last 20 years...at least! the ONLY information we had left was an affidavit from state trooper saying it was not a stolen vehicle.
We have been on the search for trying to get a title for the past 3 months. We have contacted Texas and Indiana about the information but they have told us they do not hold records back that far. So, what i really want to know is how you guys have gotten around this issue or if there is a loop hole you can help me with. Id like to drive the car to prom and graduation but it is not looking hot..and I definitely did not plan on putting an entire car together to sell if for parts or a drag car! so need some good advice please.
