The Hobbycraft (AMT) lower wings come with pre-opened holes for wing mounted bomb sway braces, but these are not appropriate for the P-40F and P-40L as they were developed for the P-40N. So, a bit more sprue-goo and then filler here.
The F and L were powered by Packard Merlin engines and had a different radiator, with the cowling being a bit squarer . Also, the Merlin had a lower carburettor intake as opposed the the Alison engine which had an upper intake. This meant that the F and L didn't have the intake on top of the nose, but had the intake below the radiator and between the twin oil coolers. What is missing is the intake extension, which I suspect was a sand filter because it had a central, circular, rotating cover that can be seen closed in some photos. I added the extension from a hollow lollypop stick and will add the cover plate later.
Also, the lower intake extends past the radiator so that there are radiator exits either side, with two flaps each. The kit provides a strange piece for this area that has flaps etched in it but then fairs into the lower fuselage. Looking at photos, I cut part of this piece to represent this area as best I can.

1. Lower carburettor intake extension
2. Two flaps each side, left in the closed position
3. Original faired in piece
I will need to add structure to fill the resulting void.

1. Detail needs to be added here
2. Inaccurate, fared in piece (not attached)
This will also be modified like the other one
Finally, all four fuselages have their exhausts added (except the Eduard/Mauve kit that has externally mounted exhausts), radiators completed, gaps filled and are awaiting their cockpits before assembling and adding the wings.
