Old Revell H-19

I have the old 1/48 Revell H-19 on pontoons in my stash. So far I have Swanny's resin cockpit, wheels (want to convert it to land) and vacuformed clear parts. Matt Swan has done a fantastic job on these parts. I don't have any spare decals to put on this bird so I will need to improvise with something close. Any particular aftermarket sheet I can order to make it either  USMC or Army? The kit decals are for USAF and look to be too thick and old.
