OK... measurements.. probably want the spring *width*, and the length 
eye-to-eye for starters.  I imagine something about the "arch" would be 
needed, too.

Then they'd probably want to know front axle and rear axle weights (put 
it on a scale at the local truck stop), your intended use, blah blah.

OverLoads are springs that are long and flat, and don't come into use 
until you really load the truck down.

Add-a-leafs are arched leaves that you add to your current spring pack.. 
it raises the truck and makes the rid rougher.
