The reason they are bit pricey is that they contain more than just a cockpit, they include a proper exhaust and nose wheel bays, (for the F-84F), and in the RF variants I include the intake splitters as well. I have completed a small set for the Tan RF with exhaust, main wheels, and corrected outer aileron that pushes the inner flaps closer into the fuselage, closing the gap that you will find there.
I also make all three ejection seats that they used.
The early type, but with the built in head armor, the AMI seat and the MB seat. Pm me if anyone needs them.
