Norman Kraus will beg to differ. He was the first to do it, showed it to Chrysler to let them know it COULD be done and Chrysler followed suit.

I’d say he showed they could be sold. Norm Kraus is a salesman.

Honestly, selling them is harder than building them.

In 1968 Chrysler designed Hemi Darts and Barracudas. And built a prototype/mule. Much harder and complex then M-code 69 A-bodies.
