I'm sure he meant a picture of the of replica you are thinking of building.
Personly,Factory Five's GTM powered by a Vette V8 sounds pretty good to me, although its not a GT40 replica.
If I where to do a replica car, it wold like be a Ferrari 250 of some sort, probably the SWB California Spyder. Although a Series ! or II GTO or Lusso wouldn't be bad either. P3/P4 would also be ok, but I wouldn't build it to scale due to how tall I am.
