I remember back in the early 90's, 02's were going for cheap in So Cal. It doesn't take much of an impact to total an 02. It's much easier for an insurance company to total an older car than deal with repairs. I had two 74 2002's declared a total loss in the mid 90's and value was around 3K each. I received checks for around 3K each minus the amount I bought them back for. First one was definitely totaled by a red light runner, I bought that one back for $125 and parted that one out. The second one was rear ended and I bought that one back for $200, fixed that one and drove it for several more years before I parted it out. After the first 02 was totaled in 1994, I bought the second one for $750 and drove it home, those days are long gone.
We need more info on what generated a rebuilt title, collision damage from 30-40 years ago? Hopefully all maintenance records are available with the car. You're going to have to go back through all the past receipts to see if you have find any receipts for auto body work. Also look for any old insurance company account #'s (proof of insurance) and contact that insurance company to see if they have any past history on claims paid out. Good luck in your search. You've got some research to do.
