Amazing progress!
I'm sure you guys have everything well sorted out but this WIP screenshot from the other page got my attention:

It looks like a bubbletop crockpit with a flap equalizer added to the pilot's right floor. If so, according to P-47D training manual AAF 50-5 this would be inaccurate:
Series prior to the D-10 contain a hydraulic flap equalizer. When the flaps are equalized--that is, when they raise and lower evenly--a plunger on the forward end of the cylincer extends between 5/16 and 3/4 inches.
Link to page.
A copy of the Pilot's Flight Operating Instructions that essentially covers every razorback variant used during the war (the bubbletops starting with the D-25 series were already in production) describes as such:
(9) WING FLAP CONTROL.--The wing flaps are actuated by engine hydraulic pressure with provision for emergency hand-pump operation. They are actuated by means of the flap control switch (figure 9-2). The pressure on the flaps is equalized by means of the hydraulic equalizer valve located on the floor to the right of the pilot's seat. (See figure 10.) This valve insures that the two flaps come down or go up together.
Figure 10--Hydraulic Equalizer Valve--(Equalizer Discontinued on P-47D-10 and subsequent models.)
* Figure 10 is a small photograph of the equalizer.
** Figure 9-2 shows controls on the crockpit's left wall.
Link to page.
Finally, I'm not able to see any evidence of the equalizer valve in the the P-47D-25 through D-35 PFOI, or in photographs of bubbletop crockpits.
If I've misinterpreted the screenshot, forgive me. Also, it is obvious that you have put a lot of effort into researching for accuracy so perhaps you have evidence that proves my argument wrong.
