I bought the one on Rockauto. It has no valve, and the rearmost connection comes up out of the top of the heater box, not the fromt like the valve does. I think you could re-work the box to make this work. However, I got a NOS valve off of e-bay. I brought the old heater core to a local radiator shop. They took the tank that the valve connects to off it and put it on the core I got from Rockauto. Back in business with an original set up.
