F4U-4 Corsair - the cowling flap actuators are different from the F4U-1

Hello all!

I'm working on the Trumpeter dash-four. I noticed in the Detail and Scale book that the cowling flap actuators on the dash-four are different from the dash one's. There is no exposed cable outside of the main fuselage linking the actuators. Instead, posts running directly from the flaps run through holes in the front of the fuselage and are linked by cable inside the fuselage. Does anyone have any detailed plans or photos of this part of the dash-four? I'd like to represent the actuators accurately.

Thanks in advance!
