G'day Sgt. Pappy!
We used Goodyear FG-1D Corsairs in the RNZAF (Royal New Zealand Air Force) from 1944-47, and apparently the only external difference was the fitting of rocket stubs under the wings (3 pairs per wing if I remember rightly.) I'm guessing the wing would have to have been strengthened for that, as even our Chance-Vought F4U-1D's could only carry weapon loads on the inner pvlons, that is inboard of the undercarriage.
All our Corsairs had the landing hook and bar removed, with only the actuating gear remaining fixed to the tail wheel leg, through which a ring was mounted where the bar would have been attached (possibly for towing the aircraft, but that's just my guess)
As far as I know the wings could still be folded on our FG-1D's, I would be very surprised if they produced Corsirs without this function.
Will let you know if I find out any technical info to help you, my books are all at home.
Hope this helps!
