Early 28 brake cross shaft

[talwrench]

Started working on my 28 roaster p/u. I encountered a different cross shaft than I have seen. Its 3 pieces. My question is, dose anything belong between the shaft and the U clamp where it is supported out at the frame? I have lots of movement front to back. Should note this is early, no seperate shaft for emergency brake, the e brake pulls on the 4 wheel brakes.
