“Fresh air enters thru the cowl vents and exits via a long slot at the base of the rear window on the cab models.”
This was one of GM’s marketing claims for the advance design series of trucks. Since I haven’t had the seat frame and fuel tank striped out of my 1950, 3604 I may be missing something. But I haven’t been able to find any “slot at the base of the rear window”, has anyone else seen this or was it only on the first models then eliminated on the later ones.
