Are Vin tags ( I already own the car) able to be reproduced?

I have a 70 Road Runner, bought it April 7, 1987. Drove it, raced it, wrecked it, and redone it.....LOL, It was registed to me,and legal.Well, I let the registration laps in 1992 I think. Car was in my garage.....in 2000, I started on the car, got a new dash, took the vins off it for the swap, stuck them somewhere........in 2004, was working on it again, new engine, trans....then my mom died.Here it is 2014, and I am NEEDING it to be mine again, BUT, if I cant find the vin for my car, can I have a new one made? I have an old registration for it, no pink, as my Xwife destroyed all of that. Is it possible? who does them? The vin should still be on the trunk area,so not trying to cheat.
Any help is welcome....my wife asked about it several years ago at the DMV, the lady said its out of the system.If I register it again, might make me work faster.LOL
Thanks,Andrew/Kidd
