What distinguished the planned British F4U-4C Corsair?

What was the difference between the F4U-4B Corsair and the planned British F4U-4C version?

Mostly minor adaptations for British carriers, probably including clipped wings, although the differences are recalled incompletely.

The proposed British F4U-4C is recalled as having relatively minor changes reflecting British carrier requirements. Clipped outer wings are suggested as a likely standard feature, but no complete specification or dimensions are established. Fleet briefly discusses a later jet before the others clarify that the question concerns the Second World War Corsair. Those jet comments do not describe the planned F4U variant.
