Alan, that's awesome! My question is: is it an ORIGINAL GSX or did he changed it to look like a GSX over the years? And is it a Stage 1??
I ask because there were ONLY 678 GSX's produced in 1970. Of those, only 491 were Saturn yellow. The production breakdown between 4 speed and automatic, along with standard 455 vs Stage 1 makes those combinations very rare indeed!
