I am making some for 1/72 Skyhawks, but, those are going to be scratchbuilt and aren't near finished yet.
You need to look out for what time period you are doing them, there is an early stubby version used on T-33s, and into Korea and the sixties,,,,,,,,,and then there is the later, longer and more slender version as used on Skyhawks, Skywarriors. For example, photos of P-2 Neptunes might have either version in them, as that aircraft served while both types were in use.
