If you don't mind not having the monitor permanently mounted in the dash, then why not just attach a rectangular piece of material shaped to fit in the cubby below the radio to the back of the screen, and then slide the mounting block combo into the cubby. A bit of foam tape or adhesive rubber strips on the mounting block would ensure a tight, stable fit. I think that would be far easier/less expensive/better looking than a separate stand with the screen mounted to it...and would have the additional benefit of being more stable if you are using a touchscreen.
