Weeds,
Here is a
photo album of Suburban body mounts. It includes photos "from below" of all mounts except the front cab mount (which is the same as on a pickup - a recessed metal "cup" on the top of the body and a pad between the body and frame).
I will post another album tomorrow in the headliner thread that you started. Sorry about the delay - I'm taking photos while I'm under the suburban removing transmission, clutch assembly, and flywheel (to have the flywheel resurfaced and balanced).
