HERE is a good source for these things, the Racing Sports Cars site--you can search by car, driver, individual race, all sorts of handy stuff.
I've linked you to the cover page for the Shelby Daytona Coupe,
HERE. In addition to the photos, you can follow the documentation to search out individual races and such.
THIS LINK gets you two nice photo galleries of the two coupes at the Watkins Glen salon in 2001, very helpful details--but you might want to cross-check the markings if you're being careful to document a particular outing for any car; they changed just about every race.
Email me at hudsonduster AT hotmail DOT com and I will send you a .pdf that details the colors and markings of Coupe #CSX2287 in each of its ten outings.
