Drawings for open try level auto rack cars

[Anonymous]

I Custom build locos and cars in 1 1/2" scale live steam. I am looking for the drawings to the open try level auto rack cars of the 1960. Have contacted T T X and got drawings for the flat car but they said the rail roads built the racks. I contacted Santafe and others but they said all of their old drawings are distoryed.Had no luck with trinty rail service either.Any help would gratey be appreciated.Mike.
