Looking for a factory spring rating

I am putting new rear springs in another project truck due to every hanger being rotten and the springs being 265k old I just figured it would be worth while to to put NEW springs in.

My problem is I cannot find what the springs are rated for, to find replacements

The rear spring code is "F"

Anyone know?

The SD spring page does not show the FACTORY spring rate is, just what they want to sell you.

The ford chart shows the F code springs rated at 3,410lb for the pair. Thank you
