Well you can do a search on www.dogpile.com or you could do a google search. But I think you'll like one of these two books that show a lot of detail.
Walk Around P-51 Mustang a Squadron Signals book.
Aero Details North American P-51 Mustang.
Both books show a lot of closeup photographs of such stuff. Aero Detail is the better of the two, I think, and a bit more expensive as well.
