Here is a fun work WIP of the IAI F-16A/B 'ACE' Upgrade. http://www.iai.co.il/17866-23270-en/Business_Areas_Military_Aircraft_Upgrades.aspx?btl=1 The cockpit is the F-22A changed to display single engine data with F-16 avionics and the Elta EL/M-2032 radar. The Skin for the prototype F-16B needs a bit more work.
