Looking for my dad's 71 Superbee

I know this is probably a shot in the dark but I am looking for my dad's 71 Superbee. It had a 383 with a 3 speed originally but my dad put a 4 speed in it at some point. From what I remember it was burnt orange or brownish color with tan interior I believe. My dad sold it in mid 80s to a friend who sold it to a guy in Sauk Centre, Mn. a year later. I haven't been able to find the VIN. I have been trying to locate this car since my dad passed away 4 years ago. I remember riding in that car with him and would really like to see it again and hopefully buy it back. If anyone has any possible info or leads please let me know. Thanks.
