 One of the major modifications made during the rebuild involved installing a more powerful Wright R-3350 (from a Douglas Skyraider) in place of the Pratt & Whitney R-2800 engine that is standard for a Bearcat.A Douglas DC-7 propeller and cowl were used and Shelton bought the landing gear fairings and doors from the wreck of Bob Kucera's Bearcat.Bill Fornoff loaned him a left wing panel and Gunter Balz supplied a rudder.
