SBP KH proportioning valve pic?

Can some one post a pic of the correct proportioning valve for the manual KH disk set up on a 72 A-body?
I want to make sure I have the right one because the only numbers I can find are -024 8 it looks just like the manual drum one that I took off the car.

Yeah Yeah Yeah, I know its not called a proportioning valve and that it is metering block with a switch in it but you know what Im talking about.
