Conversion for P-38

[Gullwing]

I am wishing to buid a photo- recon version of the P-38 in 1/48, and am wanting to locate the nose for what will be a Monogram kit. The nose I believe makes the version an F-5 . So if you could point me in the direction I would appreciate it, or if someone has this conversion part to sell then say hello...........
