Stock height for light and heavy duty F250's

[Sonoma250]

Does anyone know where I can obtain the factory heights for the heavy duty and light duty 1972 F250 4x4's? I have the lighter duty and would like to know what the difference is of the heavier duty gvw truck as well as what the factory height was of mine to see if she has settled. Thank You.

it has definetly settled. old rubber cab and body mounts will sink and then the springs over time will lose part of thier tension. yo umight check out the factory manuls to see if they have any info about it. maybe clearance heights will be all you may find.
