which of the three Phantom versions do you have "late decals" for?
if the FG 1 (or F-4K) or the FGR 2 (or F-4M), then in 1/72 scale you want to find the Fujimi kits, those are definitely what you want if the jets have the rectangular additions on the tip of the tails
if by "late" you mean the F-4J(UK) versions,,,,,,,,those can be made from any 1/72 F-4J kit from Fujimi, Hasegawa or Monogram,,,,,,,,or you could look around for some old Esci/ERTL/AMT kits,,,,,,as long as you add the intake DECM conduits to your model, and the Slime lights, but, with NO slats on the outer wings
