My thoughts;
The only difference (that I can think of) between the Suburban and Panel body mounting,
is the cross member that is in front of the rear wheel well.
On the cross member, in the upper left corner of the
Picture there is a V-shaped bracket spot welded to the cross member. There is a bolt with a washer and a square nut. I don't know what it's for The Panel truck does not have this V-shaped bracket. The V-shaped bracket has nothing to do with the body to frame connection.
I think it is for the Suburban seat mounting cups.

Suburban frames (Slow to load)
To save much money General Motors used a modified frame from a pickup. The difference is four right angle brackets riveted to the frame. These provide an attaching point for the large single unit body (Suburban and panel truck).
( All photos are taken of the driver's side frame rail.)
Pic 2 and
Pic 4 bracket is the same as
THIS and
THIS bracket.
Pic 1 and
Pic 3 bracket is the same as
THIS and
THIS bracket..
There are 5 body to frame cross members (1,2,3,4,5) starting from the front with a total of 10 mounting points.
#1 body to frame cross member is partial, it runs from the frame rail body mounting bracket, to the transmission service cover hole, on both sides.
Pic 2&4 is the 2nd mounting bracket from front.
Pic 1&3 is the 3rd mounting bracket from front.
Check attachment for reference.
