In fact, that's what I did with Maryville and Kingsport: I took Agusta69 and turned it into Maryville70, and Southern into Kingsport70. It was the tracks that I saw that there were more similarities with them and I ended up adjusting here and there, took some pieces from a track, some from another. Of course, it wasn't exactly the same as the real thing, because it was an adaptation based on the very few photos I saw, and also using a method from Thunder98 for Trenton90s: the interpretation of what the track would be at that time. To tell you the truth, my adaptations were a nice shit compared to the work of veterans (Kingsport that didn't convince me for example), but at least it's something to play with.
What if you do what JR said: take Cordele and adjust it to look like LVMS Bullring?
