Those numbers do not make sense. There were not (to my knowledge) any cars numbered as high as 99XX, and clearly a 1983 could not be as low as 3145. I wonder if that was an assigned VIN, but how they came up with a number like that is hard to imagine.
If your associate had a photo of the actual dash or trunk VIN plate, it might help, but I doubt he does.
I hope things are going well Gavin. We missed you in Pocono. Your car would likely have provided some fierce competition!
