I did mine basically the same way Jim describes below. I used a piece
of flat steel about 2" x 12" x 3/16" bent to match the curve of the
inner cab sheet metal.

I have to do this soon also. Here's my plan:
First, play around with the belt to see where the upper attatchment
should be. Get comfy, and look at other vehicles to see where the belt
goes over your shoulder. When you figure out the attatching point,
drill the hole for the bolt thru the sheetmetal. Then, make a plate of
1/8" steel, perhaps 4" x 8" or thereabouts. Bend it to fit the curve of
the inner panel, centered on the bolt hole (if possible, or offset as
necessary). Drill several holes in the sheetmetal, which will be
covered from behind by the plate. Drill a hole in the plate, and weld a
nut on the backside. Then, put the plate in place behind the
sheetmetal, and weld rosettes thru the hols in the sheetmetal.
Hopefully you can understand this description! Basically, what happens
is that the load from the seat belt attatching point gets spread out
over a large area of the sheetmetal, so the bolt won't pull thru in case
of accident.
