Neither page show a stove pipe

Thanks for posting. I had noticed that too. I tend to consider it circumstantial evidence though. I figure that graphic art stuff is done in advance and often images are re-worked versions of older media. Anecdotally, almost all of the examples I've found have been non heat stove. However my brother found this 69 CST today that I would generally consider original and fairly complete and it had non AIR exhaust manifolds and a heat stove breather. Don't know the VIN so no idea about assembly plant or relative time of production. FWIW...
