Dr Diff Offest Kit With Oval Track Springs

I had a minute so I measured the thickness of the main leaf on the AFCO 20231M’s on my Duster and the yet to be installed MP oval track springs that already look goofy (flat spot in the arch).

AFCO 20231M main leaf = .300”

MP oval track main leaf = .325”

Now what was I saying about there being more to it than the thickness of the main leaf?
