What valve bodies are generally best on 727.

No, not a transbrake car.

Perhaps I should have said a Bracket car.

Doing the work isn’t a problem, we are pretty well equipped shop for mechanicals/ body work etc.

Getting the right combo worked out and parts here to work with is the concern.
Budget is fine so far.

Fwiw- I really do appreciate everyone here- your help has been truly that- helpful.
