OK, so I reread your post and I thought you were talking about the lower bell crank positioning. I see now you were talking about the lever on the valve body. Someone else with more transmission experience can talk about different levers from other car/truck models but the levers are keyed and only go on one way. Although I could see where maybe one had been drilled out for some reason years ago...or could be drilled out as a possible last ditch fix...
