I built the very first two along time ago .............. must get this one ,and Chris to answer your Question who came first . https://www.hemmings.com/magazine/mus/2006/08/The-First-Thunderbolt---1964-Ford/1317232.html
I notice that the pistol grip shifter is wrong for a console car ,but if you leave out the console the shifter will be correct for a non-console car . but any of the monogram 1/24 Superbird, GTX, Roadrunner ...ect has the correct console sifter .
