I have been able to replace the rear ABS valve. I started with purchasing a rear ABS valve for a 1994 Chevy 4x4, 2500. I had to make some changes since the port sizes are different for the Chev. I had to shorten a transition brake line, rewire the solenoid wiring, found a male metripak 280 four prong shell, male pins and wired it as per Dodge wiring. Amazingly I am now hearing the solenoids get activated during the key ON, ABS self test.
