Had to dig out an old Service Manual;

1968 Olds 88
caster 0 deg to -1 deg

1965 Cadillac, except 75 Series
caster -1/2 deg to -1 1/2 deg

1968 Buick Skylark
caster 0 deg to -1 deg

1963 Chevy Bel Air, Impala
caster -1/2 deg to +1/2 deg

1966-68 Dodge Monaco, Polara, Coronet
W/O Power Steering; caster -1 deg to 0 deg
W/ Power Steering; caster +1/4 deg to +1 1/4 deg

1965 Ford Galaxie
caster -1/2 deg to +1/2 deg

1964 Mercury Monterey
caster -1 deg to +1 deg

I can go on, but got tired of typing.

It was mainly on the huge tuna boats. They got away with it for two main reasons; The bias tires deflected more, causing more drag, return to center and they wanted them to have as light as possible steering on their "sofas on wheels". Yes, if you put radials on them, without changing the caster, they were evil to drive, herding sheep!
