Spring eye question

I do not have any of the leaf springs with the smaller front eyes bolt (1/2") to compare......but is the OUTSIDE DIAMETER of the leaf spring eye smaller or the same OD as the larger bolt (5/8") front spring eye.

If you have the leaf spring with the smaller id ( 1/2").....can you give me a approximate measurement ? I assume it would be slightly smaller, but that can get me in trouble.

Thanks,
Denny
