There is another difference,,,but I am not sure
of the 'boundries'
It existed on the 57s and 58s also
The power brake boosters
The KELSEY HAYS (squeeze box) was the only one
available on DETROIT AND EVANSVILLE CARS
The BENDIX (cannister) I THINK,,,was used on LOS
ANGELES CARS
I dont know about the NEWARK cars
maybe you could pose this to Bob
also.
