Josh, I looked at the RF-4B in that link
It's a BuNo for a thin winged RF-4B (the first 36),,,,but I can't tell from that angle which wing it is molded as
If it's molded as a thick wing,,,,it needs markings for 157342 to 157348,,,,,as those are thick wing like C's,,,with "Angular" noses,,,,,,,157348 to 157351 are the three with thick wings and "rounded" noses, like late RF-4C's
I don't know if there are any aftermarket decals for the three different RF-4B versions, though,,,,or I'd give you a link for sure
here's a version summary of RF-4B BuNo's and types
36 thin wing 151975 to 151983, and 153089 to 153115
7 thick wing, Angular nose 157342 to 157348
3 thick wing, Rounded nose 157349 to 157351
if you want more variation,,,,after SURE and then SLEP,,,,check pics for the sensor upgrades (SURE), slotted stabs,,,,and late "J" type engines (SLEP)
you can get 6 or 8 variations of airframe appearance in the RF-4B, if you want to build something no one else has built

edit: I just thought of another thin wing RF-4 that would be cool
YRF-4C numbers 62-12200 and 62-12201, both are thin winged with Angular noses, in Lt Gull Gray and White camo, the early USAF scheme
put a gun in the Recce nose of 62-12200 and you have the first YF-4E, in SEA Camo (this is the jet that went on to fly in 2 other configurations, also, the slatted Agile Eagle, then the Canard equipped FBW)
4 different looking jets,,,,from one aircraft number
