Cassady,
The two cockpit models were originally released by ESCI, but are now available from Italeri. The F-16 cockpit is listed in the 2004 catalog of "the Squadron"( Squardron Mail Order) at $28.97 U.S., and the F-104-G cockpit is listed for $32.47 U.S. I do not remember there being an F-106 cockpit.
