Redoing the entire front disc brakes on my '73 Cuda. Is this KH Valve factory? Has anyone ever seen this stock on an Ebody? (front disc, rear drum system)

The pictured cast iron brake combination hydraulic valve is the stock type used on 1973 E-bodies.

Chrysler began switching from brass to cast iron valves in 1972 on some models. E-bodies switched to cast iron for the 1973 model year.

The following images show the combinatin valve listing from the 1973 service manual:

It's what my 73 has. I had mine rebuilt because I could not find one anywhere that didn't need to be rebuilt.
