Proportioning valve location

I am planning on installing a Wilwood single prop valve in my car to balance the disc front upgde vs. The rear drums.

Planning on using:

Can I mount this before the stock distribution block? I'd like to have It mounted on the drivers inner fender well, where it is accessible and more protected than mounting down on the frame rail like I see some folks do.

Found the same question in the post linked below asked as a response but never answered.
