Identify this proportioning valve please. I'm picking up a 94 integra rear disc conversion for my 89 CRX Si and he is including a proportioning valve, below is the picture of it. Can someone tell me what kind it is, I need a 4040, thanks.

I'm not familiar with the older models, but that doesn't appear to be a proportioning valve as a they would have at least one inlet and one outlet for each wheel, for a minimum of 5.

That is a distribution block for the rear brake lines. A 4040 proportioning valve has 2 inlets and 4 outlets. Here's a pic:

Its actually an ABS prop valve.

No, it is not a proportioning valve. Some Honda/Acura ABS systems, such as the gen5 Prelude, have an external proportioning valve which has 2 inlets and 2 outlets for the rear brakes. Other systems, such as the gen3 Integra, have the proportioning valve built into the ABS modulator. The pic is of a distribution block for the rear brakes from a system like the latter.
