Front leaf spring ID 47" eye to eye 3.18" eye width

[PaulJG]

Picked up some temporary 'mockup' front springs from a local squarebody guy selling out parts. (using on a 1969 C30 conversion)
They're 47" eye to eye..military wrap as I've heard it described. They are tapered both in width and thickness but they measure approx 3.18" wide at the eye. Didn't measure that when I picked them up..oops. Look like high quality sorings when new.
I understood Sq body front leafs to be 3" wide at the eye from last 2 I measured and whhat I've read.
Curious if these were actually square body leaf springs?
