longhorn chassis

[tpr]

Is their two types of longhorn chassis .If you look at the roll cage on the right front halow down bar some cars have a short support bar (chris maddens car) others have no short support bar but have a second bar just to the inside (casey roberts car) . This second bar at right front looks the same as a rocket xr1 . Is this just a difference in roll cages or are the two chassis different altogether .Here are pics of davenports car (inside bar) weavers car (short support bar)

They look exactly the same to me. Slightly different angles but bars look the same.
