Gary Cosgrove of Thousand Oaks acquired #2421 disassembled for $16K. He apparently is the owner who modified it with the Grp 4 flares, etc. Body work, paint, engine work, and all the custom parts brought the price of his investment to $60K. He began taking it to shows in 1986.
All detailed by Cosgrove in Pantera International magazine, Fall 1995, issue 84.
