A-Body Holy Grail???

THE "Holy Grail" of A-bodies?
That'd have to be the original "mule car", '67 Hemi 'cuda that Mopar used to develop the '68 S/S package. I was lucky enough to see it up close when it was in the McGroder collection. Very interesting some of the "revolutionary" parts they used (like a wood blocker"spacer" to move the master cylinder.
It'd have to be THAT or the original S&M '68 Cuda as it was, I believe, the no. 2 car off the Hurst assembly line......
