1965 specific coronet leaf springs

[j-c-c-62]

The front section on a leaf spring works as a locator for the axle... the rear section is your spring.

If the front spring eye is lower than the centerline of the axle you will gain "bite". If the front section is higher than the axle centerline it starts to become a " buggy spring".

Being a "pivot" and a "locator" are essentially the same description and overall denotes the uniqueness of mopar leaf springs vs other designs.
And an example of the distinction between goals "handling" and "acceleration".
A flat front leaf at rest negates mostly roll oversteer where the above "bite" orientation promotes it.
Not sure what "buggy spring" denotes.

A buggy spring is an eliptical design or a semi eliptical design.

Early Fords used semi eliptical springs on both front and rear axles.

I ran rear leaf spring dirt cars for years and the front spring eye was adustable for height via a jacking bolt so we could adjust for varying track conditions. The lower the front eye the better the bite ( within reason).
