Seeking: Short "turkey feathers" from Revell 1/32 Phantom F-4

[MrRobot]

1/32 Phantom kits come with one of two types of "turkey feathers" (the ring of exhaust cone petals): short or long. Some X-wings used the long variant, but I'm doing Red 2 and therefore need the short variant. 

Here's what the long ones look like:



Here's the short ones:

i may be losing my mind here, but i thought that was just the same part cut shorter

It's possible that they sometimes just cut down longer ones to get a match. However, there were definitely two different variants of Revell's tool and some kits have long and some have short. Curiously, I have only seen the short cones in the F-4J. I did some quick-and-dirty numbers from Worthpoint records and it's about 50% of F-4J kits (in any boxing). I've never seen them in an F-4E. So, short and long variants are out there and were certainly available to the ILMers in 1976.
